v2.0.0-beta2 - More improvements and features

Thanks to everyone who tested out beta1, and pulled from master. This addresses a couple issues that were found, and adds a few more features and improves update capability.

Changelog:

• Updating config files from previous versions more robust
• Adding some new properties/settings
• Showing release country flag if the tf.releaseCountry field is set
• Replicated theme background on theme startup so on_paint never shows white
• Stopped text now shows "foobar" and version. This is configurable and you can set it back to "foobar plays music" which was the old default
