Because certain aggregates and concatenation requires results in
a certain order, this change allows specific control of the order
features are added to the aggregate during an expression evaluation.
E.g.
concatenate("Station",concatenator:=',', order_by:="Station")
will give a comma separated list of station names in alphabetical
order, rather than layer feature order.

Updating the srs.db ------------------- The srs.db can be updated from the EPSG codes in the GDAL installation: 1) Install latest GDAL, be sure to configure with --with-python. 2) Set PATH and PYTHONDIR if installed GDAL in non-standard location. 3) Run 'scripts/qgis_srs.sh > new_srs.sql'. It may take a minute or two. 4) Run 'sqlite3 new_srs.db < new_srs.sql'.' 4) Run 'sqlite3 new_srs.db <postprocess_srs.sql' You can use sqlite3 to dump the contents from both srs.db and new_srs.db before you decide to commit.
