Patch for Gizmos and updated build settings

[marfi]

Hi Eran,
here are two patches:
- the first one updates Gizmos source code and project templates in accordance to currently used approach for handling of pre-compiled headers,
- the second one adds "-fopenmp" compiler/linker switches to the default build settings (for gcc/g++ only).

Best regards
Michal

Hi Eran,
I'm afraid you've forgotten to apply patch also for gizmos.cpp source file so the Gizmos projects using precompiled headers are now broken in CL 3408 (you have updated the gizmos templates, but not the source code). You can donwload the source and DIFF files from attachments.

Best regards
Michal
