Update to a more recent development snapshot.
This prepares the terrain and makes it in sync with the upcoming Qt5 version of
that needs a more recent version than 0.9.2. There has been no official 0.9.3
yet, so all
distributions are packaging Launchpad snapshots of the port.
In addition to that:
- Rename the GENDOCS option to the more standard DOXYGEN.
- Simplify options handling.
Most of the work has been done in our experimental area51 repository by Tobias
<firstname.lastname@example.org>, thanks a lot!
- Update to 0.6.4.
- Add some external contributions rejected by Canonical because of
copyright issues.
