Minor Updates - Uisilrao, Theron, Delphi, Kaa G!'kul

Some minor updates, hopefully nothing breaks:

Data

• Replaced Tealou Arlaoh worlds in my Dotmap Reconstruction of Uistilrao sector with data from BeRKA
  
• Added Uistilao as an alias for Uistilrao
  
• Replaced custom-generated Theron data with BeRKA's
• Incorporate xboat routes for Delphi from the JTAS Delphi Discussion (subscription required)
  
• Updated Kaa G!'kul sector data based on Mike McKeown's redux of Leroy Guatney's HIWG data
  

Rendering

• Ley Sector has IL (Imperial - Luriana Cultural) and IU (Imperial - Ursa Cultural) allegiances - map to "Im" for the purposes of rendering for map consistency (cultural regions are not generally called out on my map)
  

API

• Coordinates API now takes sector[/hex] OR sx/sy[/hx/hy] and returns (World-space) x/y in addition to sx/sy/hx/hy
  
• API docs now validate as HTML 4.0 Transitional
• Added Universe API for fetching high level data about the universe - list of known sectors
