Interactive Geo search using jVectorMap (removed OpenLayers)

Results still need work and search needs UI/style tweaks but geographic regions are clickable

Also:
- Using [bower](http://bower.io) for js/css management
- 2-way binding of region selections in directive
- fixed issue of map size incorrect on first show
- Converted the tdwg level 2 geographic region to jVectorMap format, from same shapefile used in GeographicRegion model
