Improve support for tags

[frank-lenormand]

Hi,

The log view shows tags only if they happen to point at a revision in view.

The revision view does not show that it is pointed to by a tag.

I didn’t see any obvious way of displaying all the tags in the repository either, maybe I missed it.

It’d be convenient to put more focus on tags:

• display tags in the reference view (they are stored in .git/refs/tags after all)
• have a dedicated tag view that shows all the information related to it (signing, annotation…)
• allow jumping to a tag view from the log/revision view
• showing that the current revision in the revision view is pointed to by a tag

@altsem I think it's worth adding tags to show_refs right?

Also maybe segregate branches on local and remotes like in magit?:

The issue for me is that in my company we name branches like "feature/JIRA-XXX-quite-long-description-of-the-feature" and pretty often two branches (local and remote) don't fit onto one line

So having them in two different sections would make it more neat

I agree, there's a lot left to implement on the show_refs screen. It currently won't show branches that are only on the remote. Making it behave like Magit seems like a nice pattern to follow, unless there's some great improvement to be made!
