emv 944768d277 0029312: Using OBB to speed up Boolean Operations 
1. Implementation of the user-defined option for usage of Oriented Bounding Boxes (OBB) in Boolean Operations for additional filtering (rejection) of selected for intersection pairs of sub-shapes.

By default the usage of OBB is turned off.
To enable/disable its usage the method SetUseOBB(flag) should be used. This method is available for all operations in Boolean Component.
To enable/disable it in draw the command "buseobb 0/1" should be used. Note, that this will affect all subsequent operations.

The OBB for the shapes are built by first necessity and stored into operation context (IntTools_Context).

2. Usage of the OBB in some test cases.
