Lightweight Java Game Library Code

Split the external LWJGL version from the internal version of the native JNI library. The internal JNI version is now an integer. This has multiple advantages over the old way:

1. The JNI_VERSION field is now included automatically in the generated JNI headers, relieving us of the burden of updating the version number in both java and native code.
2. We can update the JNI version with every non-compatible change of the JNI library API, not just once per release, giving us extra safety when users download and build LWJGL from SVN.
3. We can now avoid rebuilding natives if a particular release only
contains java changes. Currently, This is mostly a problem when Brian bumps the
external version prior a release and I forget to re-build the natives ;)

remove .cvsignore files

Windows: Use the standard _WIN32 macro instead of the LWJGL defined WIN32.

Fix compile warning

Windows: don't cache the JNIEnv pointer in the message handle, but acquire it through the global JavaVM handle.

Added a native NewStringNativeUnsigned to avoid compile warnings

Linux: Moved most input related stuff from native to java
