Latency of map display

[georgio8]

There is now a lag of ~ 4 secs on opening LCC's consultation map. This is mainly due to the large number of AJAX calls to the Cyclescape server (about 70 of them) to get the issues for TfL and each borough:
Possible actions:

• batch up the AJAX calls to the CyclesScape API
  ** E.g. could do this with a single call getting all the issues in Greater London, then sorting them on the client side.
  ** a solution where the server does most of the sorting work would be better (simpler and more responsive).
• Minify the scripts

Write a spec and ask Nikolai to implement it in the API.
