Fire destroy-inspector event when a zip is dropped on the canvas fixes #1278559
Merge pull request #118 from makyo/relation-menu-2

Relation menu now shows icons based on aggregated relation status.  Additionally, endpoints as listed in the menu are styled per each endpoint's status (endpoints in error are shown in red).  Action remains delete, for now, but all other actions remain available through inspector.

QA with `/:flags:/relationCollections`, deploy Mysql and Wordpress, bump Wordpress to 100 units, and wait for a relation error.  Check that the menu displays proper icons and colors endpoints based on error/running status.
