ShellOut Versions Save

This release enables a custom Process instance to be injected when calling shellOut.

• A race condition that could occur when capturing output data is now being avoided (by @helje5)
• ShellOut no longer closes standard file handles (like stdin and stderr) when finishing (by @SteveBarnegren)

This version migrates ShellOut to Swift 4.2

ShellOut is now thread safe thanks to @harlanhaskins 🎉

• ShellOut now uses Swift 4.
• copyFile and removeFile has been added to the convenience API.
• You can now use paths containing a tilde to refer to the home folder.
• More user friendly descriptions of errors.

This release fixes build errors on Linux, since attaching handlers to FileHandles is not yet supported in the Swift standard library on that platform.

• You can now capture the output of STDOUT and STDERR by injecting your own custom FileHandles.
• ShellOut now supports pre-defined commands (using ShellOutCommand), and ships with a suite of commands for common tasks.

New features

• Run a series of commands at once
• Run either a single command or a series of commands at a given path

See updated README for usage examples of the above

Fixes

• Documentation fixes (thanks @pixyzehn!)
