Misc Bug Fixes and a New Helper Function

This update fixes an issue where public shares could show resources that weren’t enabled when the share was created and resources could appear outside their proper folder. It also fixes an issue where a modal dialog could appear below an unscheduled event popover. We’ve also improved the behavior in horizon view when breaking out by a date field so the breakout sections are now sorted by the breakout date.
For developers, this update also adds a new helper function for custom actions allowing the use of mutation observers to detect when dom changes occur.
