Fix compilation:

- /GL vs /ZI conflict for CrashHandler and SendRpt
- missing parameter in gitdlltest.cpp + documentation of the follow parameter in gitdll.h
- disable Edit&Continue compilation for ssh.c (as written in the comments)
- add missing #includes
- add missing AdditionalIncludeDirectories
