* Fix right-click options for unregistered extensions
* Show only "Call Voicemail" option
* Fix caller id number cut-off too early
* Fix drag-and-drop request rejected
* Always show "My Extensions"
* Fix showing caller id on unregistered called extension
* The voicemail icon and caller ID information now shows for a call routed to the unregistered extension.
Also, hide the intercept option if the caller is the current operator extension because the operator can't intercept their own call.
* Fix: extension has multiple call groups
* Fix outgoing and incoming calls section.
* Use browser caching for css file with cache busting
By allowing the browser to download the css file directly, the browser will automatically cache the file. The `?v=` parameter uses an md5 hash to differentiate changes in the file.
Minor change requests implemented that were forgotten:
- Removed the line between the extension that belong to the user and the other extensions.
- Added the permissions for the tabs so they are not visible yet. "Extensions" and "Calls" are the only ones with the permissions after running app defaults
