Support ctools content_type

This module doesn't work when displaying a field through Ctools content_type plugin, shipped in the CCK package. One of the consequences is that aliases are never used when a field is added to a panel page using a field content pane.

Maybe instead of triggering the alias substitution through hook_nodeapi(), this should be done at a lower level. I've tried to look up documentation about CCK hooks but couldn't find anything that would allow file_aliases to trigger as soon as any field is being displayed...
