Notable Improvement in Memory Management

[Gustavo L Conte]

Lately I have noticed a much better memory management in the program as a whole. I'm used to long hours even days with a same session opened, and I can assure, not in a objective way, but by actually noticing, that memory consumption and management has improved big time.

• Use own thread for lyrics parsing -> this surely fixed something regarding to that

I don't remember other commits, but the cover/context ones surely made a huge benefit.

So here's my cheers for that, we don't need to post just trouble here but its good to recognize when things improve, its a lot of effort from Jonas to keep this a stable project with so many features to deal with at the same time. Strawberry RuleS!
