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

60af337c3c [processing][FEATURE] Add "Save Log to File" algorithm for models 
This algorithm saves the contents of the execution log (right up to
the point in the model at which the 'save log' algorithm executes)
to a file.

It can be used to automatically store the debugging log when running
models for later reference and transparency.

320fecce00 [processing] Add method to encode and decode a combined provider key and uri 
to a single string

We need this to allow processing inputs to load non gdal/ogr/mdal sources, such
as being able to directly read postgis layers without loading them into a project first

dee6f3f30d Add flag to allow a child algorithm's results to prune back the remaining model branches 
When an algorithm returns this flag, and after executing it in a model it doesn't set a
certain output which remaining model algorithms depend on, then these branches are
pruned back and don't get executed for the model run.

Allows for creation of algorithms which impact the overall model flow.

2a1bf56493 [FEATURE][processing] Remember parameter values between model designer runs 
When designing a model, users typically will need to run the model
many times as they tweak its structure.

This change causes the parameters used when running the model from
the designer to be remembered and saved into the model, so that
each time you run the model from the designer you don't have to
re-set all the input parameter values to the desired test ones.

Makes iterative model design SO much easier!

and can be freely moved around the model.

5f533e561c [FEATURE][processing] Add algorithms for raising warnings and exceptions from models 
These algorithms raise either a custom warning in the processing log, OR raise
an exception which causes the model execution to terminate.

An optional condition expression can be specified to control whether or not
the warning/exception is raised, allowing logic like "if the output layer from
another algorithm contains more then 10 features, then abort the model execution"

61454c67cd [processing] Add api to allow providers to report warnings which should 
be shown to users when using that provider

This can be used to return a translated warning message which should be
shown to users of this provider. It's intended for use in cases such as
a provider which relies on a 3rd-party backend, where the version of the
backend software is not officially supported, or for alerting users to
providers in a "beta" or "untrustworthy" state.
