Documentation drive

[xoft]

I'm resurrecting this thread from the dead. The documentation has become lacking again. There are many new classes that have none of their functions documented (projectiles, entities). I therefore urge everyone to write documentation together with writing code. And to practice, we should all try to complete the documentation. After all, it is even used while developing plugins - ZeroBrane Studio reads it and provides code completion and infotips based on it.
