Stop using nickname and use Jaberid instead

applications/hubl#906

I 'll give details later

Old accounting Protocol

Stop using nickname on MUC & one-to-one, instead technically use the jabberid. Visually, we want to show the full name of the user from the vcard.

@manv for token estimation.

Ref. #253 (comment 54586)

@manv are you this one ? Thx

@Cyrilthiriet 100 tokens

• Show the full name of the user in messages
• Rework the mention system to target the full name instead of the muc nickname

The latest part is kind of heavy hence the tokens
