Mylyn-Mantis connector 3.1.2 released

A few bugs sneaked in the 3.1.1 release - which should’ve been named 3.2.0 due to its new features -  so 3.1.2  a small bugfix and stability release is now out.

Noteworthy fixes:

1. All repository dates were incorrectly parsed . This also had the unpleasant side effect of always considering the tasks stale, which slowed operations a lot.
2. We now properly retrieve and set the ‘assigned’ status for bugs. This is important for both non-English installations and for projects using custom statuses.
