MPS-20112 gen tracer: can't use the tool: try to navigate to the node of user interest, rather than to template's input/output; cosmetics - don't show model name in the phase, too cumbersome
Expose node id from SNodeReference, otherwise there are frightful casts to SNodePointer everywhere; drop SNodePointer casts
TemplateModel: update template to re-use code which is too generic to be generated each time. Rebuilt all generators with compiled templates with new TemplateModel implementation.
Drop superfluous SNodePointer casts
Merge remote-tracking branch 'origin/master' into 3.2/artem/default
