fix getdp.i with new case convention (python wrap)
New case convention (GetDP.h -> getdp.h) was not propagated to getdp.i (pyhton wrap)
In addition, there is an API problem with GmshInitialize() in Kernel/MainKernel.cpp. There is a new call to gmsh::initialize(), which does not seem to exist in Gmsh... is there a missing commit somewhere :-)?
