Code review comment for lp:~mzanetti/ubuntu/vivid/qtsystems-opensource-src/inputinfo

I think we are going to move to a new upstream snapshot (it was requested by seb128 and kenvandine), I have already committed that to lp:~kubuntu-packagers/kubuntu-packaging/qtsystems-opensource-src.

Also, we can't remove qstorageinfo right now because it was added to qtbase only in 5.4 which we don't have yet (and ubuntu-system-settings uses that class).
