tweaked portal levels plugin. reduced level markers and prefer high level portals.
experimental code: alternative marker rendering system, using canvas to create icon marker bitmaps, displaying as an L.Icon
Merge branch 'master' of https://github.com/jonatkins/ingress-intel-total-conversion
turn off markers during zoom animations - let's see how that works...
add some (very) basic checks for "error: 'missing version'" from the server
only done in the game score update code - but this is run early, and just once, when loading IITC. it also refreshes at intervals
moved experimental alternative marker plugin - it performs very poorly on mobile compared to the regular SVG circle markers
another piece of experimental marker drawing code - not 100% working. committing for future reference if needed
