Fixed mac specific compiler errors and cleaned up Objective C code

Browse source 
Created new file src/gui/macutilities.mm, moved code from mainwindow.cpp and torrentcontentmodel.cpp that used the Objective C runtime into it and converted it to actual Objective C. Rewrote pixmapForExtension() so that it doesn't call into private Qt functions.
