Update og_audience to 5.x

Patches to port this module to Drupal 5 are welcome!

patchak has arranged for me to update this module to 5.x. Can I have CVS access? Otherwise, can you branch for 4.7 so that a patch for 5.x can be applied to HEAD?

Here's my basic plan for using the API:

- we don't want to call node_save() to make these updates, or directly mess with the {node_access} table.

- for the node access system part, we can use the node_access_acquire_grants() function to update the node access table.

- for the og part of this, we will use the og API function og_save_ancestry() to get og to update its tables.

Digging into the code- one observation: the current code only allows re-assignment if the node already belongs to a group. I guess there is no good way to set the "Public" setting if it's not already part of a group?

Attached patch updates the module for 5.x. I think it's RTBC, based on my testing. Note new settings page and black, as well as updated REAME.

Unfortunately, I won't be able to do a proper review right now, but you now have cvs access, feel free to use it. :-) Thanks for this work, and sorry for the lack of feedback so far!

Ok, no problem. The API calls might be useful if you need to update OG Public Access.
