Movement of Capabilities class and chooseCapabilities functionality into NativeWindowFactory introduced an undesirable dependence between the windowing toolkit, which can be replaced via NativeWindowFactory, and the library which implements the selection algorithm, for example OpenGL. This would prevent, for example, an easy SWT port of JOGL.

To fix this, refactored chooseCapabilities into new
GraphicsConfigurationFactory, the default implementation of which is
currently a no-op on X11 platforms, and which is provided by JOGL in a
toolkit-agnostic manner via GLX. Refactored OpenGL portions of
Capabilities class back into GLCapabilities. Reintroduced
GLCapabilitiesChooser interface for compatibility and to avoid having
to import javax.media.nativewindow classes in most user code.

Fixed problem in GLProfile where failures to load native libraries
were being squelched. Reorganized build to have all outputs under
build/ directory.
