Fixed Issue 44: Add pbuffer-based GLJPanel implementation

Fixed Issue 61: Make debug variables load from system properties

Added a hardware acceleration path for GLJPanel implemented using the
GLPbuffer interfaces. If instantiation of the pbuffer fails, the
GLJPanel implementation attempts to catch the resulting exception and
fall back on the existing software rendering path.

The new code has been successfully tested on Windows. This checkin
attempts to make the needed changes to the pbuffer implementation on
other platforms, but the GLJPanel continues to use software rendering
until all platforms can be tested.

Additionally, references to static final DEBUG flags have been made
settable via system properties. "jogl.verbose" enables certain
printing statements. "jogl.debug" enables all debugging printing.
"jogl.debug.GLContext" enables the debug printing inside the GLContext
class. The system property names are chosen by convention and are not
enforced.
