Allow auto tests to stay away from the user's configuration.

QStandardPaths now knows a "test mode" which changes writable locations
to point to test directories, in order to prevent auto tests from reading from
or writing to the current user's configuration.

This affects the locations into which test programs might write files:
GenericDataLocation, DataLocation, ConfigLocation,
GenericCacheLocation, CacheLocation.
Other locations are not affected.
