+- Added the emote feature to WorkAdventure. (@Kharhamel, @Tabascoeye)
   - The emote menu can be opened by clicking on your character. 
   -  Clicking on one of its element will close the menu and play an emote above your character. 
   -  This emote can be seen by other players.
 - Mobile support has been improved
-    - WorkAdventure automatically sets the zoom level based on the viewport size to ensure a sensible size of the map is visible, whatever the viewport used
-    - Mouse wheel support to zoom in / out
-    - Pinch support on mobile to zoom in / out
-    - Improved virtual joystick size (adapts to the zoom level)
