Note: there is no user interface for editing the owners list.
It is supposed to be done through the API (to be done)

Added tabs for 'edit' or 'review' mode. 
The Django view checks if the user may view
shared annotations for the anobj. The layout
react accordingly.

Added the possibility to allow or not the members
of an AnObj to publish their annotations for
the other members. Read/write support from
AnObjMgr

AnObj sharing and permission at Backend level
AnObjMgr in FrontEnd allow editing of the sharing
properties. Is able to liste shared AnObj

Added feed back if no images to display

Zoom is centered on the mouse pointer when done
whit the mouse wheel

Added button for 100% and fitAll in the TB, fixed
