annotate src/plugins/plugin_xep_0163.py @ 1316:8adcdf2cdfe1 frontends_multi_profiles

core: added a "profileConnecting" method check: if a plugin has a profileConnecting method, it will be called when the profile is being connected but before the client stream is started. That can be usefull if things need to be done before the communication is started: e.g. putting triggers, loading PersistentDict, etc.
