Feature: Track title splits

[dikamilo]

Hello, I added track title split feature. This is simple idea that I use in foobar2000 from long time and that I miss in Simple Last.fm Scrobbler.

This adds a list of text phrases that will be removed from track titles. For example:

Split list: [Premiere]
Track title: Armin Van Buuren feat. Ana Criado – I�'ll Listen [Premiere]
Track title after split: Armin Van Buuren feat. Ana Criado – I�'ll Listen

I know that there should be a correct track title but if someone uses a lot of cue files from live sets and radio shows, this will be great feature.

My commit adds:

• new setting entry "Title Splits"
• new activity with splits list + context menu (delete item) + activity menu (add new, clear all)
• SplitsDatabase class that uses sqlite db
• modify TrackBuilder to use SplitsDatabase filer function on track title

Ah, cool. I'll read over your code in the next day or so.
