GLProfile: Initialization fix and clarifications ( GLExceptions on n/a profiles )

- GLProfile.initSingleton(boolean) (implicit or explicit) won't
  throw any exception anymore. Followup 'GLProfile GLProfile.get(..)'
  calls will throw a GLException, if n/a.
  Availability maybe queried via GLProfile.isAvailable(..).

- GLCapabilties, GLCanvas, GLJPanel: Clarify case where GLException maybe thrown,
  i.e. no default GLProfile available on default device.

- Remove redundant GLProfile.is<ProfileName>Available(..)
