Since there (currently) is no interactive widget on mobile, there
is no point in compiling it. This was a bit more complicated than
expected, since there were other source files (divehandler.cpp
and ruleritem.cpp) which reference ProfileWidget2 and therefore
need to be removed. Otherwise, the dreadful MOC produces unresolved
references.
We could now remove all the conditional compiles in
profilewidget2.cpp, but let's keep them for now. We might have
to readd a number of them later, when making the mobile-profile
interactive.
