Added org.lwjgl.opengl.AWTInputAdapter which enabled use of Mouse and

Keyboard with AWTGLCanvases. Programs can now avoid implementing AWT input processing and access the mouse grabbing features from both Display and AWTGLCanvas. See org.lwjgl.test.opengl.awt.AWTInputAdapterTest for an example.

Note: This commit is the linux and generic AWT imlementation and can still
change a lot while implementing windows and mac os x.
