GLCapabilities enhancements: Choosing, All-Available, Data Handling (X11, WGL and EGL)

- GLDrawableFactory exposes:
    public final List/*GLCapabilitiesImmutable*/ getAvailableCapabilities(AbstractGraphicsDevice device)

- GLCapabilities platform specialization containing native ids (XVisual/FBConfig, PFD, EGLConfig, ..)

- GLCapabilities setPbuffer(true) disables onscreen

- Capabilities setOnscreen(true) disables pbuffer

- Capabilities implements Comparable

- *Capabilities: enhanced 'toString(..)'

- CapabilitiesChooser.chooseCapabilities:
     'CapabilitiesImmutable[] available' -> 'List /*<CapabilitiesImmutable>*/ available'

- VersionApplet, GLCanvas.main, GLWindow.main, GLProfile/debug: dumps all available GLCaps

- WGLGLCapabilities: proper non-displayeble (pbuffer) pfdid handling

TODO: ES/EGL test with emulation
