* [feature] QgsSettings QGIS QSettings replacement
This is the new QgsSettings class that adds an (optional)
Global Settings additional ini file where a system administrator
can store default values for the settings and provide
pre-configuration.
If an ini file named qgis_global_settings.ini is found
in the pkgDataPath directory it is automatically loaded,
this path can be overriden by a command line argument
( --globalsettingsfile path ) and through an environment
variable (QGIS_GLOBAL_SETTINGS_FILE).
