Add support for FreeBSD

Improved device donfigurability, enhanced profiling, several performance and usability enhancements

Porting the wiki to github

Add support for FreeBSD. As we use the ocl-icd loader, we do not know which vendor OpenCL has, hence: FreeBSD was my choice. That being said, generic or Khronos would also be suitable.

Added JNI-side caching of compiled binaries per kernel per device
Added java-side support for control of binary caching
Added facility to cleanUpArrays() in a kernel, frees (most of) GPU memory associated with a kernel but retains JINContext to allow kernel reuse

Add parenthesis around conditional expression

beta version of Device configuration changes and introduction of KernelManager - reverting some accidentally commited files
