Support for album FLACs/Cues

[GlitchWalker]

First, I put my hands up: I'm one of those weirdos that stores his music as full-album FLACs.

I scan my computer, enter the collection, and the expected behaviour would be to correctly select and play tracks from within these files a separate tracks in the collection. However, they don't exist in the collection at all; not even as misidentified one-track-per-FLAC.

This is literally the only missing feature holding me back from using Tomahawk as my main music player. The behaviour occurs in both 0.8.4 and the 0.8.99 nightly, on Windows 10. I get if it's not high on the priority list- in which case see this more as registering my interest in said feature ;)

Besides this, the player honestly blows me away. Up to this point Clementine had been my all-in-one, cross-platform player, however it lacks working Spotify and Soundcloud support these days.

Also including log file in case it is any help (renamed to .txt as GitHub didn't support uploading a .log file)

Absence of the subj feature blocks me from using Tomahawk.
