Adds a few new enhancements:
1. Each box now has two links, clicking the rev shows the file (new), clicking the changelist shows the changelist
2. Compact option allows the non-merge/branch revisions to be hidden
3. When a revision range is merged (except on add/branch if the first rev is #1), the first rev is indicated by a red line that intersects the mid point of the line from the end rev. Looks kinda likea funnel.
