Support for Bean Block Entities!

Attached you'll find a patch that adds a ccl_bean module, which supports Bean blocks created by the Bean module. Beans are blocks, but blocks aren't Beans ;) Beans are entities, so they have bundles, entity id's, view modes, etc.

The module supports all options the code node selector has, plus these:
* Option to add a link to all but the selected Bean
* Option to add a link to all but the selected Bean, but limit that to the bundle of the selected Bean

Future additions:
* View mode support
* Bugfixes ;)
* Translation updates/fixes

I've copied a lot of code from the ccl_blocks and ccl modules, which I refactured somewhat. I'll try to make some patches for those modules too as I fixed some bugs.
