Added regions and resource_regions tables
Fix unit tests
Change block to accept integers instead of string
Fix resource index and show pages to display regions and home regions
Set up form to accept nested attributes
Fix controller to create joins for resource_region on edit and create.

I'm not sure if this is the most elegant way but it seems pretty simple. Convert params to an array, find all regions
and shovel into an array, the make resource.regions = array.
Add button class to region divs so that it will have mouse over functionality
