More win64 fixes

Remove long usage, long is still 32b on win64.

Update Readme description with mingw64-gcc link problems,
it will link without errors with MSVC libs but seg fault in runtime.
Makefile not needed anymore
exported more clu functions, updated cl_basic to skip some crashing fields
Merge branch 'dev' of github.com:tonyrog/cl into dev
Make it more version agnostic

Load OpenCL 1.2 functions dynamicly

Because otherwise I can not build the dll on OpenCL 1.2 and
run it on nvidia cards which only supports 1.1

Make device versions steer function version calls
Merge branch 'dev'
