Please note that make commands are chainable. For a typical programming loop, `make clean dev run` is very useful.
* all - Make a release binary in the build folder
* clean - Remove intermediate build files
* dev - Make a development binary in the build folder
* run - Run the current binary in the build folder
* release - Make a release binary, with the appropriate resources compiled in. Makes an app bundle on OS X, and adds the icon to the program on Windows.
