core, memory, bridge: added profile password + password encryption: /!\ This changeset updates the database version to 2 and modify the database content! Description: - new parameter General / Password to store the profile password - profile password is initialized with XMPP password value, it is stored hashed - bridge methods asyncCreateProfile/asyncConnect takes a new argument "password" (default = "") - bridge method asyncConnect returns a boolean (True = connection already established, False = connection initiated) - profile password is checked before initializing the XMPP connection - new private individual parameter to store the personal encryption key of each profile - personal key is randomly generated and encrypted with the profile password - personal key is decrypted after profile authentification and stored in a Sessions instance - personal key is used to encrypt/decrypt other passwords when they need to be retrieved/modified - modifying the profile password re-encrypt the personal key - Memory.setParam now returns a Deferred (the bridge method "setParam" is unchanged) - Memory.asyncGetParamA eventually decrypts the password, Memory.getParamA would fail on a password parameter TODO: - if profile authentication is OK but XMPP authentication is KO, prompt the user for another XMPP password - fix the method "registerNewAccount" (and move it to a plugin) - remove bridge method "connect", sole "asyncConnect" should be used
