50b723ce7b [FEATURE][processing] Add menu to the Model Designer "View" menu 
allowing users to zoom direct to any group box present in the model

Allows for simplified navigation of complex models

4fa9083cf6 [FEATURE][processing] Allow creation of group boxes in models 
These are a visual guide, allowing designers to create logical groups
of algorithms relating to a single task ("eg 'Prepare data')

The title and color of the group boxes can be customized

5963b90f2c [processing][FEATURE] After running a model through the model designer, 
show the obtained values for all child algorithm outputs within the designer
canvas

This gives users better tools for debugging models - they can see exactly
what values were output by the child algorithms and flowed into other
parts of their model

681d12e549 Tweak snapping logic, and add explicit action to "Snap Selected Components to Grid" 
This is useful when a user doesn't want to enable the auto snapping, but wants to line
up stuff nicely by hand

7d0b476fa7 Move almost all the remaining Python code for model graphic items to c++

required because they call objects which depend on Python compatibility
for deprecated API calls...
