1.0.x update to 1.1?

[tsw]

use the same upgrade path as with other versions

-backup
-overwrite files
-run install/upgrade.php
-enjoy

also remember to check that your modules are up to date and its also good to check that they work on 1.1

1.1 changes a lot of things, so there might be some problems, but thats why you took the backup in the first step
