1.1.90

After almost 7 years without releases, Tagaini is back! This release is limited to Linux users and people willing to compile from source, and is targeted at making sure that nothing is fundamentally broken before releasing 1.2.0 more widely. Also I need to figure out again how to produce Windows binaries. >_<

The biggest updates of this release are a long-overdue port to Qt5, and a better way to deal with entries deleted from the JMdict. These two issues, along with me getting busy with other things, are what held this release for so long.

Please test and report any issue (or success!), and we should be back soon with 1.2.0.
