-> now raise a PermissionDenied

-> for a TTP shared, accept registration

Display URL and label for ttp shared objects

DRF:
	Updated permission check for Annotation (compatibility with v3.*) using PermissionClass
	Added a TTPAuthentication class (adim_ttp.authentication.TTPAuthentication) so api call can be done without user token

AnObj Manager:
	Updated the properties panel for TTP shared object: the link for editing the object in the distant service is more visible

The TTP permission classes are bulit from settings, no need for hardcoding.
