Improve tag support in Diffusion
Summary:
- When viewing a commit, show its tags.
- For commits with many tags, show a list of all tags on the tag list interface.
- Improve some handling of symbolic references.
- When tags contain content, show it on the browse view reached by clicking the tag name.
Test Plan: Looked at commits with and without tags, clicked "More tags...", clicked tag names.
