Redmine

I was testing migrate_from_trac.rake and found that it was not importing the user database from trac.
I substituted ".save" with ".save!" in a few places in the script and found this error:

Validation failed: Password is too short (minimum is 8 characters)

Changing the default password for created users from 'trac'
to 'tracmigratetoredmine' fixed the problem.

See attached patch.
