Added
* (GUI) Support for BBCode in manga descriptions.
Any BBCode will now render correctly as HTML in the manga view.
* Dependency on bbcode.
* `.sync()` method to `utils.Config` (save config changes).
Changed
* (GUI) The visual layout has been changed a bit to prepare for viewer support.
* The `desc` field of `models.Metadata` is now a dictionary map of a language code to the localised description.
Fixed
* Configuration was not synced across `utils.Config` instances (i.e language), so newer configs would get overwritten by older ones.
`utils.Config` now will have only one instance to prevent this.
* (GUI) Cover images now scale correctly and no longer look pixelated, especially those of high resolution.
