Editorial metadata on calendar

This is my take on adding editorial metadata to the calendar. The calendar "post" overlay now includes links on editorial metadata that can be updated. When a user clicks on the link, the static metadata will be converted into it's corresponding input/select/textarea. The user can then edit that metadata and click save, which will save the metadata and regenerate the overlay with the new metadata.

I'm definitely open for alternatives on how this could be implemented. I just whipped this one up over the past day or two as a possible option.
