Converter incomplete

[BillyWM]

The automatic conversion script is almost, but not entirely complete. As I recall, it should be functional once it handles statics + constants; at that point it should be able to automatically convert all of Flixel's .as files to a .js file full of classes.

It won't, however, be guaranteed to correctly convert users' games, as it takes a lot of shortcuts.

Consider writing a proper parser with Jison to allow people to convert games in-browser, and even unzip them with a JS unzip library
