Add sector data loader from SOE API

Because SOEs api uses a different way of rendering the map, this uses
hardcoded ID->name mapping for sectors which we can then use to match
into our sector polygons.

build/generator builds this mapping file (use via jake gen-sectormap).
ps2hq.data namespace to contain data loaders from SOE APIs.

Updated sectors.js for Indar sector names to match the ones used by SOE.

Updated index.html to show a demo usage for SectorControl loader.
