0023670: Support for multiple 3D views: edited commands: vinit; added commands: vclose, vactivate, vviewlist

bugs/end script was edited to dump results from all opened views; duplicated vinit was deleted from bug625. QABugs::OCC280()
was edited to work with multiviews;ViewerInit() method was corrected. vviewlist command was modificated to output string.
Small corrections
Compile errors were corrected
