core: add get_*_unit functions with explicit unit system

Browse source 
The get_*_unit() functions return the unit-name as set in
the preferences. Add versions with a "metric" parameter.

This will be used by the statistics code, which may in
the future allow for binning with alternative units.

All the unit-formatting functions should probably be moved
away from qthelper to their own source file.
