Comment 12 for bug 695235

> Hummm, using QDesktopServices::storageLocation(QDesktopServices::DataLocation) seems complicated because this path is defined in depends.py (a python script), not in cpp.

Yea, part of this change would be to no longer provide SETTINGS_PATH as a compiler define. i.e. change this line:
https://github.com/mixxxdj/mixxx/blob/master/src/util/cmdlineargs.h#L74
to call QDesktopServices.

> last question : do we still need to support windows XP ? It is completely unsupported by MS for more than a year now, so why do we need to still care ? probably it's time to have windows vista as a minimum requirement for mixxx.

Sorta -- we have a ton of XP users is the thing. 1.12.0 will likely be our last XP support release.
