Added sign-in modal
Lots of changes in here.

Basicly, the css files  have been moved to one single file called new-main.css.
Also, some common graphic elements such as buttons and boxes have been scripted as a
less mixin in variables.less      and helper classes have been introduced in new-main.css.

Every page now has an id defined in the body tag.

The Google maps autocomplete fields now rewrites itself with the 'route' value
returned by google so we don't have to work with two fields, one for searcing
and another for submitting.
