remove maxZoom leaflet setting - as it overrides individual map layer settings - fix#466
ensure map zoom is valid for selected base layer - replicate functionality removed from current leaflet
this way, if you switch back to IITC, then quickly move/zoom (as often is done), unnecessary network requests are avoided
because of the change, there's no need for chat to have it's own resume hook - it already hooks into the refresh code and this is now triggered quickly
- nicely centered. few tricky css hacks
- minumum width - ready for additional content below the image
- fix & in portal titles from showing as & sequence, etc
should fix issues with layer control on mobile, and other improvements
also - the convention for marker filenames has changed from ...@2x.png to ...-2x.png for the double sized ones - so changed our files to match (we had a mix of ...@2x.png and ..._2x.png)
Core changes
* window_management.js => panes.js (clarity, distinction from dialogs)
* Make portal preview use dialogs instead of the large preview "window"
* Use `open' callback instead of `create' callback for all dialogs
* Replace collapse/close buttons with themed buttons inspired by the AP Gain plugin
* Dialogs can now gain and lose focus, with changing title bar
* Tweak the Poslinks window to use dialogs
* Add collapseCallback, expandCallback, collapseExpandCallback, focusCallback, and blurCallback
* Fix http <img> in About dialog that caused Chrome to complain
Plugin changes
* guess-player-level 0.4.1: Use dialogs with titles, typo fix
* portal-counts 0.0.8: Use dialogs with titles, typo fix
* portals-list 0.0.12: Don't hijack every single dialog onscreen, add titles, typo fix
* scoreboard 0.1.8: Use dialogs with titles
- increase timeout on zoom/move end to 0.8 seconds
- prevent repeated refreshes faster than every 5 seconds
- delay initial refresh on load - should prevent immediate refresh after page load
fix#200
add google terrain layer - max zoom possible here is 15
I did try experimenting with higher zoom for the MapQuest tiles. there was some success at 19, but not all tiles would load - reverted for now
alternative to merging #212
