Patches in the TracForge (Multi-project support for Trac) branch "Small bugfixes"
- Source the list of projects from the master database instead of patrolling the filesystem. Faster *and* cleaner.
- Don't bomb out during the 'Project Index' action if we find something unexpected
- Fix up a variable error related to switching to getting the list of child projects from the DB
- Cast self.uri_root back to a regular string so that nobody gets upset about Unicode (trac-hacks#1037)
- Switch to using env.project_url in the project index when appropriate so we can get useful links to our other projects
