Bug 9525: Add option to define float groups and rules for float

Bug 22284 introduced ability to create hold groups.
We should have ability to create float groups in
same manner. This patch adds checkbox "Is local
float group" to group creation feature and new return
policy "Item floats by librarygroup".

To test:
1. Add new float group and some libraries to it.
2. From circulation and fine rules, set default
return policy as "Item floats by library group".
3. Check out an item for a patron.
4. Set library as one that belongs in the same
float group.
5. Check in the item.
=> Observe that notice for transfer doesn't pop up.
6. Check out again.
7. This time set library as one that doen's
belong in the same float group.
8. Check in.
=> Observe that notice for transfer pops up.

Experiment this feature by changing return policy
per library, item type etc.
