* Initial pass at a global actions instance queue

* Action card with a bunch of functionality that needs to be pared back a bit

* Happy little actions button

* runAction performs updated to use actions service

* Stop All and Clear Finished buttons

* Keyboard service now passes element, so we can pseudo-click the actions dropdown

* resizable sidebar code blocks

* Contextual actions within task and job levels

* runAction greatly consolidated

* Pluralize action text

* Peer grouping of flyout action intances

* ShortIDs instead of full alloc IDs

* Testfixes that previously depended on notifications

* Stop and stop all for peered action instances

* Job name in action instance card linkable

* Componentized actions global button

* scss consolidation

* Clear and Stop buttons become mutually exclusive in an action card

* Clean up action card title styles a bit

* todo-bashing

* stopAll and stopPeers separated and fixed up

* Socket handling functions moved to the Actions service

* Error handling on socket message

* Documentation note: need alloc-exec and alloc-raw-exec for raw_exec jobs

* Tests for flyout and dropdown actions

* Docs link when in empty flyout/queue state and percy snapshot test for it
