Your task

Our frontend contains some source files written in Objc++ for some OS X functionality. Your task is to move every *.mm file in QTfrontend/platform, update the build system (.pro and CMakeLists.txt) and fix the deprecation warning.

Deliverable

A working patch, that applies cleanly to our source tree. This patch should be in the form of a pull from clone, hg export or unified diff format (in order of preference) implementing the functionality required.
