pushing in-progress visual changes
fixed problems
merged glamrock and jrb's code
added full height maps and changed default zoom levels for leaflet *WORKAROUND* so that it will work correctly.
added multi-icon support as well as icon scaling support. still need to remove autoconfigured shadows in scaled icons as well as event types for each icon (as icons for markers are pulled directly from event type.)
added some width support and refactoring icon sets to not pull default's that are not included.
The final touches to icon sizing and a comment on the possibility of calculating up front instead of on every load in case this fails stress testing.
fixed untracked exception from an old variable
added bounding box support for zooming so that low zoom areas do not default to the background when a user requests too high of a zoom level.
symbol display and etherpad links
nyanclouds added by request
