ea06500caf Port Unique Values algorithm to new API
Improvements:
- by default output a table with unique values, instead of a HTML
file. This allows the values to be more easily used in follow up
analysis (e.g. in a model). HTML output is still available, but
not output by default

b7f888bf5b Port Distance Matrix algorithm to new API
Enhancements:
- support source/target layers in different CRS
- output layers with geometry (i.e. keep input point geometry - avoids
need to rejoin result back to original table to get geometry)
- keep original data types for id fields
- don't fire off many single feature requests - instead request
multiple features at once to improve speed

11475c621d Revert "Merge pull request #4562 from alexbruy/processing-singletomulti-3"
This reverts commit e3d79a1fe940b5d813b5f79c51b43393d085bb16, reversing
changes made to 3f7f95ee262ea3646d61600c21faed0866bc70b0.

Reverting again, as Travis started failing after merging PR (with all
test passed) into master branch

1cf0a20267 [FEATURE][processing] New algorithm for topological coloring of polygons
This ports to old (pre 2.0!!) topocolor plugin to processing. It's based
off my beta 2.x fork (never publicly released) which implemented
a bunch of improvements to the algorithm allowing for minimal number
of required colors and also balanced counts of features assigned
each individual color.

** Pretty sure this plugin was highlighted in Victor's presentation
about plugins-which-shouldn't-be-plugins-and-should-be-processing-algs
instead. It's a prime example of a plugin where the amount of code
required for gui+setup exceeded the actual "guts" of the plugin by
a huge factor, and which is much more useful when it can be
integrated into a larger processing model.

91eea30e7d [FEATURE][processing] Algorithm to find an unknown layer's projection
If you have a layer with an unknown CRS, this algorithm gives a list
of possible candidate CRSes which the layer could be in.

It allows users to set the area (and corresponding CRS) which they know
the layer should be located near. The algorithm then tests every CRS
in the database to see what candidate CRSes would cause the layer
to be located at that preset area.

It's much faster than it sounds!! (just a couple of seconds)
