v0.2.0 - Better multi-user support.

There are very few visual changes with this release, but a few bigger and less visible changes since the last tagged version make it much less problematic to use this login screen with a large number of accounts listed. I don't think many users have enough accounts to encounter issues with the previous release but regardless its a nice touch and could make the screen feel a little more authentic.

I've been using this version of the login screen myself for over a month without issues now and haven't encountered any major issues. With less time to make minor refinements and no urgent problems to address it makes sense to version the current state of the project.
