Move printGpsCoords from MainTab to QtHelper

Last time I touched this I got a scream from dirk, but then I
looked at the code again and the problem that I faced was that
I broke translations in a sad way, well, now I broke it again.

However, this method shouldn't belong to MainTab ( because of
that thingy that I said before and also many others: Separate
the logic of your application from the UI specific code )

This generates a string that's going to be used on the Interface,
it doesn't display it on the interface. Move it down below makes
it easier to test ( I don't need to create an Widget and worry
about the parent-relationship with the mainwindow just to test
this function, for instance. )
