Upgraded some more dependencies

Continuing on, I've upgraded most of the dependencies to use the latest version. See commit log for details.

Some comments:
- I left the majority in -core alone, since it looked like most of them were included to verify those versions are indeeded marked as vulnerable.
- `mvn clean install` still runs sucessfully, though since I don't have mono installed, the .NET related tests have been ignored (Cool, haven't seen Assume used in practice before). Someone might want to doublecheck those are still working.
- When upgrading h2 to the 1.4.x-series I saw some failing tests because they couldn't connect to the database. From their homepage it looks like this is still in beta (http://www.h2database.com/html/changelog.html) so I went with the latest 1.3.x instead. I didn't look more into it, but should probably do so if a stable release of the 1.4.x-series show up.
- Apache Lucene also has some newer versions, though switching to these caused compilation errors. I might look more into why, but thought I'd deal with the upgrades which didn't require code changes first.
