[extending] basic version of authorization rules

[admin]

[extending media mediamosa module] At the moment no authorization rules are available in this module. With MediaMosa authorization rules can be very specific. For this version we only need the following:
- a textarea per node where author can add domain names
- let MediaMosa check the domain when a end-user requests the video

Because very often the domain will be identical per node, there should be a default settings form.

Robert,

1) please do the general review from our repo:
 http://hg.saga/mediamosa/media_mediamosa/

2) I need your advice with editing node. Seems that even if we already have mediafile attached to a field, in _media_mediamosa_change_cck we are creating a new mediafile ID by calling
_media_mediamosa_upload_prepare() .
It prevent my code to display correctly already assigned rules in the editing form. See my comment in _media_mediamosa_access_create_form, line 395 of media_mediamosa_helpers.inc
What shall we do about this? Shall I modify core code to track this change or we assume that user never editing files?

Thanks!
