In this commit, we update the UI to:
* Display emoji on the buddy list (right side sidebar).
* Display the emoji picker on the set status overlay.
It also updates the `z-index` of
`#set_user_status_modal`, which was changed from 105
to 1050 in 166bfa4cf8. We change it back to 105, so
emoji-popover can be visible on top of the
`#set_user_status_modal`.
We also remove the `tabindex` property from the
`#set_user_status_modal` so it can allow keyboard
events for emoji popover.
The chevron sometime can be confused as an icon for expanding the
stream topics especially for the new users.
This commit replaces the confusing chevron icon from the stream-sidebar,
topic-list, user-presence-row, all-messages and starred-messages with
ellipsis-v icon(vertical three dots).
Fixes: #7115
Hovering over user names (and user circles for PM List) now displays
Name, Status Message and Last online time in a js tooltip.
Hovering over group names displays the names of all group members.
Unavailable users are shown as "Last active: Today".
Hovering on a user circle in the Buddy List results in a js tooltip
with Active/Idle/Offline/Unavailable for
green/orange/white/white-with-line.
Resolves#11607.
