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: Compile fixes

Win32: Fix Mouse.setCursorLocation()

Win32: Ignore SC_*MENU messages (triggered on ALT and F10 and made LWJGL apps appear to hang)

Win32: Implemented Mouse.setCursorPosition()

Win32: Fixed 64 bit warnings in Mouse.c

Win32: Always sepcify WS_CLIPCHILDREN | WS_CLIPSIBLINGS in window style flags, since it is required for SetPixelFormat to work (according to MSDN docs)

Win32: Handle all Windows messages, and ignore those with inappropriate HWNDs

Win32: Confine cursor to fullscreen window to prevent native cursors to stray outside borders in multi-monitor setups
