Nyall Dawson f602ed3751 Add API to allow setting the default view extent for a new project
Allows a QgsProject created using QGIS api only (i.e., not via the desktop
application) to specify the default extent which should be visible when
that project is opened.

Straight from the dox:

Sets the default view extent, which should be used as the initial map extent
when this project is opened.

\warning When a project is opened in the QGIS desktop application and saved, individual
map canvases will store their own previous view extent as custom project properties. Reloading
this saved version of the project will trigger the canvases to restore their individual last view
extents. Accordingly, in the QGIS desktop application, this setting only forms a default, initial
view used when the project is opened for the very first time.
