v1.2.0

This release has a faster startup time by loading the library data from a file which is saved each time a full scan is completed.
After startup, a background full scan is started asynchronously.

There is now a second type of continuous play mode called "Tag" which instead of random, will select a song sharing at least 1 tag with the current song, if one exists, falling back to random.

What's Changed
