This is the change in plain SQL:
INSERT INTO tbl_datum_transform VALUES (7709, 100018, 4277, 4258, 9615, 'OSTN15_NTv2_OSGBtoETRS.gsb',
null, null, null, null, null, null, 'UK National Transformation provided by Ordnance Survey',
'For applications requiring an accuracy of better than 10 centimetres.', 1, 0, 1264);
INSERT INTO tbl_datum_transform VALUES (7710, 100019, 4277, 4326, 9615, 'OSTN15_NTv2_OSGBtoETRS.gsb',
null, null, null, null, null, null, 'UK National Transformation provided by Ordnance Survey',
'For applications requiring an accuracy of better than 10 centimetres.', 1, 0, 1264);
(one still needs to manually download the .gsb grid file to use it but at least no need to modify system srs.db)

- copy descriptions, preference and deprecation from GDAL
- remember position of dialog
- allow hiding of deprecated transformations

- QgsDataProvider&QgsMapLayer: add dataChanged() signal, so that a provider can signal that the datasource changed
- use QNetworkAccessManager instead of QgsHttpTransaction (including caching and
dynamic authentification to website and proxies)
- resolve EPSG dependency in spatial reference systems and
included french IGNF definitions in srs.db
- wms provider:
- do request asynchronously through QNetworkAccessManager
- add support for WMS-C
- dataChanged() is to cause a redraw asynchronously, when new tiles arrive
- wms selection:
- add support for WMS-C tilesets
- allow inserting of all layers of a branch
- add support for more mime types
- move load/save to button box
- and more cleanups
- raster provider: reduce debugging noise
- allow adding parts to multi points and lines

* Added a small README on the process on how to do the above
* Change the CRS recognition when reading from projects, so it tries to match the proj4 string if valid. This is a must when the srs.db now is updated
* Changed to read ellipsoid an projection acronyms from srs.db nistead of qgis.db (mostly)
* Misc. clean up of comments and deletion of stale code.
* Fixes#1534.
