Lightweight Java Game Library Code

OpenAL: Made the openal library path returned by the current ClassLoader and cwd more override java.library.path. Converted some printfDebug to printfDebugJava

Win32 part of refactor and AWTGLCanvas

Win32: hardened getAvailableDisplayModes

Converted win32 specific native source from C++->C (removes the strange debug flag behaviour exhibited by SourceLimitTest.java)
