move poppler-0.24.5 to the appropriate SLOT
stupid oh-my-zsh- shortcut did only remove the old version...
Here is the most recent updated poppler
Add qt-creator-3.0.0 built with Qt5.
It would depend on qthelp, but I did not find a way to only extract
necessary additional dirs (for qt-clucene), so I simply added a
monolithic "assistant-5.2.0", to quickly get qt-creator pushed.
