55027e545f Clean up and extend expression geometry functions: 
- New expression functions for area(geom), perimeter(geom),
point_n(geom), start_point(geom), end_point(geom), make_point(x,y)
- Add new variant to length() function which takes a geometry object,
allows for length(geom) evaluation.
- Rename x_at, y_at to $x_at, $y_at (alias old names) to reflect that
these only work on current feature geometry
- Add x(geom), y(geom) functions which return x and y coordinate
for point geometries or centroid x/y for non-point geometries
(fix #11008)

709c14391b Change expression help from free form html files to structured json 
A new script then parses these json help files into the html help
contents, in a standardised manner. Previously, the function help
was a bunch of different formats and structures.

Now, a custom stylesheet can be applied (and later tweaked!) to
format these help. Eg, this commit colors variables and function
names in the syntax section for greater readability.

7871d6c5fc Remove a bunch of layer variables, replace with new layer_property 
function

layer_property takes a layer name/id and a property (eg 'crs')
and returns the matching value. This approach is more flexible than
having all these values as variables, since it allows retrieval
of properties of a layer from contexts which aren't layer-aware
(eg a composer label showing the metadata of a layer).

feb3bee858 Add a bunch of optimised fuzzy string matching algorithms. 
A new QgsStringUtils class has been added containing some
common fuzzy matching algorithms, including Levenshtein edit
distance and Soundex. These can be used for finding "similar"
strings in a table.

Expression functions for these algorithms have also been
added to a new "Fuzzy Matching" group.

0af69ed9fb Add pertinent example for 'LIKE' operator 
The usage examples for the 'LIKE' operator are not really pertinent. The proposed change adds an example that actually illustrates the usual usage of the 'LIKE' operator.

96db1bdb7e Allow expression functions to include 0 length parameter lists 
This change allows for some cleanups to the built in expression
functions, by making it possible to differentiate variables
(eg $feature) from functions which don't require parameters
(eg uuid(), now()... ). Also adds aliases for uuid(), now(), and
pi().
