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.
mod_base: added 'is_result_render' option to 'moreresults' action. Allows render of all results at once instead of per result item.
mod_geomap: export lookup functions, add hard coded lookups for exceptions.
Perform country lookups by iso code - works better with OpenStreetMaps API.
mod_base: fix hybi00 websocket connections. Fixes #637
