Boar should be able to handle old read-only repositories

What steps will reproduce the problem?
1. Create a repository with a repo v0 version of boar (boar-daily.11-Jul-2011 
or earlier)
2. Make the repository read-only by changing the permissions or burn it to a 
dvd.
3. Try to check out the contents of the repository.

What is the expected output? What do you see instead?

The operation should complete normally. Instead, an exception occurs because 
the repository can't be upgraded to the current format due to write protection.

A workaround is to copy the repository to a location where it can be modified 
to allow the repository to be upgraded.
