AixLib now is on the right export version

Again a new release to adjust and support the right version numbers of the supported modelica libraries.

Now the modelica export should work again with the actual AixLib version

There has been a bug in the TypeBuildings XML for TABULA (concerning Windows), this should be fixed now.

Pre-release status
We want to state, that this release is a pre release and so a (maybe) non stable version with bugs. It is not that havily tested as the other releases. As the enhancements are great we have nevertheless decided to publish this release. So apologies for that.

Release Notes
We are happy to publish the following release notes:
- Tabula Typebuilding integration for Germany
- Deleted the GUI (can't keep up maintenance for that)
- Support of all IBPSA core library extensions ([Buildings](https://github.com/lbl-srg/modelica-buildings), [IDEAS](https://github.com/open-ideas/IDEAS), [BuildingSystems](https://github.com/UdK-VPT/BuildingSystems), [AixLib](https://github.com/RWTH-EBC/AixLib))
- Added usefull return statements of the Project class
- PEP8 (thanks to thorade)

Since AixLib's master is currently on version 0.5.2, this release updates the reference version in TEASER to this version. In this way, Modelica environments don't try to call a conversion script.
