Minimap enhancements!!

Much of this patch comes from upstream and Kitty Barnett, or is inspired from their works
This commit applies the World-Minimap patches from Catznip.

Catznip stuffs:
- Issue 1383: Parcel lines on mini map
 - Show parcels on the minimap
 - Minimap menu: "Show" submenu: "Property Lines" "Parcels for Sale"
- Option to have world map textures on the minimap
 - Minimap menu: "World Map Textures"
 - Singular touch: Made this comply with hypergridding.

The minimap will now scroll zoom based on where your mouse is if centering on camera is off.

A lot of cruft was cleaned up in this merge, a lot of gSavedSettings lookups in draw were converted to LLCachedControls, some license updates were performed.

Finally: By myself, but inspired by upstream and requested in the group before:
- Option to show tracking circles around people selected on the radar while the radar is visible
 - Minimap menu: "Show" submenu: "Radar Tracking Circles"
