Added Mitigation column

Added mitigation column to portals list
bugfix: run setLoadingState on UI thread in CheckHttpResponse
added status bar tap to the info-screen hint
draw-tools: update edit colour to match that used while drawing - with only dashed lines being used as in stock Leaflet.Draw
first attempt at updating munge parameters for new niantic intel site update
have commented out old munges for now - they don't include parameters needed in some new requests, so are unlikely to be used again
for #589
quick fix for chat, for protocol changes
for #589
remove old factionOnly flag from chat requests. although the stock site appears to send it still at first glance of the code, this appears to be incorrect - and sending it causes old messages to come first rather than new ones!
(perhaps i've mis-identified the flag - and it's the one for getting older messages first?)
for #589
factionOnly was not correct - had mis-entered this mapping (and was already there for ascendingTimestampOrder - it's real meaning)
reduce faction messages to 50 at a time - as they're no longer cluttered with user-specific alerts
(these now appear in a separate 'alerts' tab on the stock site - yet to be implemented in IITC)
website - remove old URL from commented out 'IITC broken' section
another mungs set was pushed live. update the code
also reordered munge list to match the order found in the stock page (makes it easier to update) and tweaked the code that detects and auto-tries munge sets
fixed typo
