Changed qt5 to fetch from gitorious

Added the possibility to specify commit SHA of the qt module.
NOTE: webkit is fetched from qt.gitorious.org/qt/qtwebkit as a
simplistic measure. It will switched to the correct location
once it is available. To build Webkit additional dependencies
are required, these are "flex bison gperf libicu-dev libxslt-dev
ruby libxcb-fixes0-dev libxcb-rand0-dev"
