Osk Sdl Versions Save

• Refactored Makefile (#69)
• Replace Surface by Render API (#78)

Releasing this, so the version we package in pmbootstrap doesn't diverge much from the version in this repository. On a side note, nowadays it is possible to build the package with source code from the checked out git folder:

$ pmbootstrap build osk-sdl --arch=armhf --src=/path/to/git/checkout/of/osk-sdl

• Improvements to rendering (#62) a356914

• Add script to help with running osk-sdl in pmOS 3dfa00e

Fix segfault on unclean quit

• Remove workaround for upstream SDL2 bug

• display error message on incorrect passphrase

• Move license to GPLv3
• Remove SDL_INIT_JOYSTICK flag from initialization of SDL2

• Makefile changes
• add 'verbose' option: -v
