Version 0.2.0 released

I said I wouldn't spend more time in this prototype project, but I received a couple of good suggestions for improving the game that were relatively easy to implement, so here we are.

What's new?

• Added custom skin autoloading feature. If the game finds a "custom" folder next to the game executable, it will try to automatically load the files inside (textures and audio) as custom skin.
• Added sound effect and bgm customization. The game will now load custom sound effects and background music placed in the same folder as the textures. Only mp3 files are supported.

This should be the definitive version of the game, unless there are critical bugs that need fixing.
