Allow user to switch to tag

Right now you can switch to any branch within a project, but you should also be able to switch to any tag. Maybe within the same spinner, maybe via some other UI?

Added Feature label

Milestone changed to 2.2.6

I think that we will have a custom Dialog that allows you to see all branches and tags and switch to any of them which would then update the subtitle in the toolbar

@Jawnnypoo Keep in mind that any dialogs you add should be built using MaterialDialog (see https://github.com/afollestad/material-dialogs) for proper theming, as app-theme-engine doesn't properly tint AppCompat dialogs for now.

Milestone changed to 2.2.7

Status changed to closed
