removed CLContext factory methods with CLPlatform + CLDevice list combinations.
justification:
 - information is now no longer needed since every CLDevice knows its CLPlatform
 - OpenCL device IDs are not portable between CLPlatforms

changes:
 - Context factories will throw CLInvalidPlatformException if the platform of all CLDevices does not match

related changes:
 - [persistance] CLProgramBuilder stores now the ICD suffix to be later able to map binaries back to the platform + device

fixed exception message in NDRange Kernel method.

wait timeout for concurrencyTest; context release try-finally bocks for all other test methods.

CLCommandQueueTest: fixed invalid work group size error on low spec devices

wait(timeout) should return boolean.

CLGLContext.create() makes GLContext current (restored old behavior).
CLGLTest:  make gl context current right after init (jogl bug workaround)

adjusted remaining work group sizes in tests.
