mod_geomap: load cluster popups via template. Disable google geo lookups for half an hour if quota exceeded. Cleanup of some js code. Perform geo lookups in same process as pivot, prevents too many parallel lookups when re-pivoting.

(cherry picked from commit 559cb01b5ada625652a4626e15fc49ba1698d378)
mod_base: added 'is_result_render' option to 'moreresults' action. Allows render of all results at once instead of per result item.
