Fix Unicode handling in OGDSUpdater
Reworked PasteItem tests (use ftw.testbrowser instead of OGBrowser).
Adjust available expression for paste action.

Use `object` instead of `folder` to call the `is_pasting_allowed`, because it's
not guaranteed that all folder allways returns the current context.
Disable paste action for mails.
Make sure metadata-fix profile is always installed last as policy-depencency.

The order specified in metadata.xml is not guaranteed, thus we hard-code
the depencency in the deploy class and install it once the policy has been
installed.

Make sure metadata-fix profile is always installed last as policy-depency.
Create repositories from generic-setup folder instead of single file.

This moves repository creation in one place taking filename as repository-id.
As a side-effect it adds the possibility to create multiple repositories at once.
Make sure repositores are first in content order.
