Fixed periodicity issue by addind STOPPER_OUT_OF_GRID_PERIODIC flag. Further preparaions for stress BC

Added configBoundaryLayer.txt. Added Slip BC allocations to GridGenerator. Can now be used again, but thus far ignores normals and uses the default q's set by the SideType. Modified NoSlip BC, now just adds a velocity BC with zero velocity.

adds wrapper for gpu WIP

As the cuda warnings are different on each platform and super badly documented, we switch to suppress all warnings for the GridGenerator.

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