-Implemented ping feature front-end.
-Started on custom minis and tablecloths
-Added custom minis and custom tablecloth interface. Really need to unify the front-end dialogs (some of them are now jQuery dialogs, and some are customs. It would be nice if they were all the same; it would make it easier to close inactive ones, and the jQuery ones get shown properly if the user scrolls around. The ones I'd want to convert are:

-zoomed card
-new-table overlay
-deck editor)
