due to the changes in the kernel factory the includes and calls in the numerical test framework are also changed

changed the naming of the missing Classes (Strategies) and added the chimera kernel from the open source code

Bug fix in density correct terms. Multiphase velocity BC has been simplified for this early stage of the development.

simplified the kernel factory infrastructure by omit the enum (Kerneltype) -> adding new kernels to the factory should be straightforward now

Implements surface tension following Hesam's code. Also corrects uninitialized variables in MultiphaseCumulantLBMKernel::findNeighbors . This might have influence on the contact angle. Initialization is now set to zero!

Implements pressure and stress correction for multiphase model with density contrast. Pressure is regularized and hence different from the form used by Safari and Fakahri. Surface tension is not implemented.

Implements cumulant phase field function and a passive incompressible momentum equation. The phase field is only coupled to the fluid velocity but there is no featback to the fluid. Only as a starting step for further developments.

Fix various msvc compiler warnings. With msvc the compiler flags are explicit passed to nvcc with -Xcompiler.

 - metis: do not pass -O3 flag on msvc compiler, as this flag is ignored anyway. Instead of /w pass w0, which is equivalent to /w.
 - RheologyK17LBMKernel: A and B are also defined in D3Q27System.h. Therefore to not hide this declaration they are renamed to A_ and B_
 - additional small clean ups...
