core, frontends: refactoring to base Libervia on QuickFrontend (big mixed commit): /!\ not finished, everything is still instable ! - bridge: DBus bridge has been modified to allow blocking call to be called in the same way as asynchronous calls - bridge: calls with a callback and no errback are now possible, default errback log the error - constants: removed hack to manage presence without OrderedDict, as an OrderedDict like class has been implemented in Libervia - core: getLastResource has been removed and replaced by getMainResource (there is a global better management of resources) - various style improvments: use of constants when possible, fixed variable overlaps, import of module instead of direct class import - frontends: printInfo and printMessage methods in (Quick)Chat are more generic (use of extra instead of timestamp) - frontends: bridge creation and option parsing (command line arguments) are now specified by the frontend in QuickApp __init__ - frontends: ProfileManager manage a more complete plug sequence (some stuff formerly manage in contact_list have moved to ProfileManager) - quick_frontend (quick_widgets): QuickWidgetsManager is now iterable (all widgets are then returned), or can return an iterator on a specific class (return all widgets of this class) with getWidgets - frontends: tools.jid can now be used in Pyjamas, with some care - frontends (XMLUI): profile is now managed - core (memory): big improvment on entities cache management (and specially resource management) - core (params/exceptions): added PermissionError - various fixes and improvments, check diff for more details
