plugin XEP-0384: update to last python-omemo + trust management: - Plugin has been updated to use last version of python-omemo (10.0.3). - A temporary method remove all storage data if they are found, this method must be removed before 0.7 release (only people using dev version should have old omemo data in there storage). - Trust management is not implemented, using new encryptionTrustUIGet method (an UI is also displayed when trust handling is needed before sending a message). - omemo.DefaultOTPKPolicy is now used, instead of previous test policy of always deleting. OMEMO e2e encryption is now functional for one2one conversations, including fingerprint management.
