Crimes Against the JVM

Caching improvements

Changes how bytecode is read. Now you place filenames - relative to config/catj/ - in books, which then get parsed & executed.

This has the benefit of being significantly more secure (data never touches the server) AND easier to edit (you don't need a whole new book every time you screw up!)

Add a verify pass before loading the class for real

Remove unused Knot reflection :3

Oops. Use getString not toString :3
