Fix Bug 600 and Bug 721: Adding support for multiple monitors w/ NEWT

- Support for all monitor devices and their available modes
  - X11: Use RandR 1.3 if available
  - Retrieve information
  - Changing a monitor device's mode

- Support for dedicated and spannig fullscreen
  - See <http://jogamp.org/files/screenshots/newt-mmonitor/html/>

- TODO:
  - X11 RandR does _not_ relayout the virtual screen size
    and neither the CRT's viewport.
    We may need to relayout them if they were covering a seamless region
    to achieve same experience!

  - OSX: No machine to attach a secondary CRT -> TEST!

- Tested Manually for Regressions
  - Linux ARMv6hf (Rasp-Pi/BCM, Panda/X11)
  - Android (Huawei, Kindle)

- Tested Manually and junit:
  - X11/Linux
    - NV, ATI-Catalyst w/ 2 CRTs
    - VBox w/ 4 CRTs

  - Win/Windows
    - NV, w/ 2 CRTs
    - VBox w/ 4 CRTs

  - X11/OpenIndiana, NV, 1 CRT
