Implement footermap as a block instead of only allowing it to be in the footer

Issue Summary

Hi, I downloaded footermap today, and it was almost exactly what I wanted, except that I wanted to be able to include the map as a block in the footer section of my theme, but the module was sticking the map in the "closure" area. I modified the module to implement the map as a block instead, that you can put in any region of a theme. This seems like a much more flexible approach to me! Attached is a patch that achieves this behavior.
