backend, frontends: message refactoring (huge commit):
/!\ several features are temporarily disabled, like notifications in frontends
next step in refactoring, with the following changes:
- jp: updated jp message to follow changes in backend/bridge
- jp: added --lang, --subject, --subject_lang, and --type options to jp message + fixed unicode handling for jid
- quick_frontend (QuickApp, QuickChat):
- follow backend changes
- refactored chat, message are now handled in OrderedDict and uid are kept so they can be updated
- Message and Occupant classes handle metadata, so frontend just have to display them
- Primitivus (Chat):
- follow backend/QuickFrontend changes
- info & standard messages are handled in the same MessageWidget class
- improved/simplified handling of messages, removed update() method
- user joined/left messages are merged when next to each other
- a separator is shown when message is received while widget is out of focus, so user can quickly see the new messages
- affiliation/role are shown (in a basic way for now) in occupants panel
- removed "/me" messages handling, as it will be done by a backend plugin
- message language is displayed when available (only one language per message for now)
- fixed :history and :search commands
- core (constants): new constants for messages type, XML namespace, entity type
- core: *Message methods renamed to follow new code sytle (e.g. sendMessageToBridge => messageSendToBridge)
- core (messages handling): fixed handling of language
- core (messages handling): mes_data['from'] and ['to'] are now jid.JID
- core (core.xmpp): reorganised message methods, added getNick() method to client.roster
- plugin text commands: fixed plugin and adapted to new messages behaviour. client is now used in arguments instead of profile
- plugins: added information for cancellation reason in CancelError calls
- plugin XEP-0045: various improvments, but this plugin still need work:
- trigger is used to avoid message already handled by the plugin to be handled a second time
- changed the way to handle history, the last message from DB is checked and we request only messages since this one, in seconds (thanks Poezio folks :))
- subject reception is waited before sending the roomJoined signal, this way we are sure that everything including history is ready
- cmd_* method now follow the new convention with client instead of profile
- roomUserJoined and roomUserLeft messages are removed, the events are now handled with info message with a "ROOM_USER_JOINED" info subtype
- probably other forgotten stuffs :p
