Bugfix release

Changes:

• modified the macOS GUI idle animation to reduce CPU usage during the application idle stage (issue report #66)

This release includes a large number of changes across all applications in the Crunch repository. crunch executable users should rebuild the project dependencies to take full advantage of the changes in this release. See the executable upgrade documentation for details.

Changes:

• improved quality of pngquant quantization of PNG images across all file sizes
• upgraded embedded pngquant to v2.12.0 (includes reduced pngquant optimization times)
• converted to custom build of zopflipng that is modified for use in the Crunch applications (forked from google/zopfli at git tag zopfli-1.0.2) at git version tag v2.1.0 (source repository is chrissimpkins/zopfli)
• improved zopfli compression ratios for post-quantized and non-quantized in-file sizes under 350kB. Many files are ~33% original file size after they are quantized with pngquant so this affects pre-optimization files up to just over ~1MB in size when the pngquant step is completed (the quantize step yields a modified image binary when it does not lead to larger file size or image quality below Crunch project thresholds, when this does not occur the original file at the original file size is used as the in-file to zopflipng)
• improved zopfli compression speed for post-quantized and non-quantized in-file sizes over 750kB
• eliminate optional PNG chunks by default in all files (reduces file size)
• converted to use of PNG filter = 0 for zopflipng compression of all quantized files (increases compression speed)
• use automated detection of best PNG filter for zopfli compression in all non-quantized files (improves compression)
• remove hidden colors behind alpha channel 0 in files that are not quantized due to low quality or increased file size following pngquant runs
• added new macOS GUI animations with success and fail indicators (thanks Gary Jacobs!)
• added logging of compression data and errors in macOS GUI and macOS right-click menu service tools in a new log file that is generated on the path ~/.crunch/crunch.log
• updated redirect to /dev/null in install-dependencies.sh compile script for POSIX compliance
• refactored command line option parsing code (thanks Chris Clauss!)
• added new bug reporting template

Changes:

• added automated detection of png image types through read of PNG file signatures (issue #45)
• removed testing for *.png file extension to process files (issue #45)
• added support for simple modification of pnquant and zopflipng paths that are used for optimization, convert to system PATH installed versions by modification of the Python script (issue #40)
• bugfix for macOS GUI and right-click menu service failures with absolute file paths that contain multiple directory levels with space characters (issue #47)

Changes:

• bugfix for failed image optimization with macOS GUI and right-click menu service tools when spaces are included in absolute file paths (issue report #30)

Changes:

• bugfix for failed image optimization on pngquant execution that leads to file sizes below min acceptable (issue report #25)

Changes:

• new crunch executable that supports parallel PNG image optimization on *nix platforms (including macOS, Linux, and POSIX compliant application environments on Windows such as Cygwin)
• parallel image processing support added to the Crunch macOS GUI application
• parallel image processing support added to the Crunch Image(s) macOS right-click menu service
• updated embedded pngquant executable to v2.11.7 (January 2018) with statically compiled library dependencies
• updated embedded zopflipng executable to git tag zopfli-1.0.1
• convert Crunch macOS GUI files to binary (from XML text files)
• new make target and shell script for pngquant dependency source compile support for *nix platforms
• new make target and shell script for zopflipng dependency source compile support for *nix platforms
• new make target for pngquant dependency uninstall
• new make target for zopflipng depdendency uninstall
• new make target for command line executable install
• new make target for command line executable uninstall
• new make target for Python script testing
• new make target for shell script linting
• fix for make target install of macOS right-click service over a previous install

Changes:

• added a new macOS right click menu service for Crunch PNG image optimization named "Crunch Image(s)"
• added Makefile with target support for macOS service installs and uninstalls
• reformatted About menu text
• added Upgrade documentation to the About menu
• new source repository macOS service documentation, docs/SERVICE.md
• repository documentation updates

Fix for #7

Changes:

• include statically linked dependencies in pngquant compile at pngquant v2.11.7 (https://github.com/chrissimpkins/Crunch/issues/7)
• update dmg-installer.sh shell script to automate creation of dmg installer SHA1 checksum files
