Bootstrapped HomeMap to main.js

We were having a problem with requirejs
loading modules from a url other than the
one that was configured. The reason being that
we were using an unconfigured global object 'require'
to initialize our maps. This global object didn't
know anything about our defiened paths and trying
by default to load modules from /static/js
Eliminated app.js file and include the main

initialization script in main.js
