Support for multiple languages open simultaneously

[chaver1]

For keeping multiple dictionaries open simultaneously. So for example if maintaining dictionaries of closely related languages, it'd be nice to be able to flip between the two dictionaries rather easily without requiring the closing of one dictionary before opening another. So tab support is ideal for that, but multi-window support is also great in my view.

A corollary to this, referencing words in another dictionary in the system for etymology or loan words for example could be a really great feature.

(Sorry for bombarding you with feature requests, I just got lots of ideas lol)

I'm going to have to put some thought into this feature, it might be one that is a few releases down the road. I can see why it's useful, but given how a lot of the existing UI works, it'll be tricky to implement. For the moment, it might make the most sense to simply have two instances of PolyGlot open at the same time.

Also, don't sweat all the suggestions/requests! Interactions like that are exactly how I make the application better/more stable. :3
