Project templates should be stored relative to config folder

Affected QGIS version: 2.8.1
Redmine category:project_loading/saving

The path to project templates is currently stored absolute in the .ini config file. So when preparing a default config to be used with the --configpath option, the templates will be searched in the absolute (often wrong) directory, rather than in the relative one.
Better make absolute/relative optional, or follow the choice for project layers.

The same applies to a lot of settings related to Processing (e.g. paths to providers like SAGA or GRASS) and also model or script folder.
Would be nice to be able to have variables available here or if paths to providers could be read from PATH...
That would make --configpath more portable between different computer (and possibly OSes).
