- selected rows in the Tools Tables will stay colored in blue after loosing focus instead of the default gray

- in NCC Tool the Tool name in the Parameters section will be the Tool ID in the Tool Table
- added an exception catch in case the plotcanvas init failed for the OpenGL graphic engine and warn user about what happened
