change QtVersionManager::instance() return type to QtVersionManager*

Enough time has passed to make developers acquainted to the static
methods of QtVersionManager. Returning the correct type in the instance
method has the following advantages:
  - signal/slot autocompletion is working again
  - Qt5's type-safe connect syntax becomes usable without casting to
    QtVersionManager*
