* DistUpgrade/DistUpgradeControler.py:
- always enable "main" on upgrades, this ensures that we do not end up
with a system without the main archive (various bugs for breezy->dapper)
* data/channels/Debian.info, data/channels/Ubuntu.info:
- added pre-generated files (required for the upgrader)
* UpdateManager/Common/aptsources.py:
- add a "matcherPath" parameter to SourcesList (for the upgrader)
