config file + cleaning: - SàT Pubsub can now be configured using the same config file as SàT itself (i.e. sat.conf or .sat.conf), in the same locations (/etc, local dir, xdg dir). Its options must be in the "pubsub" section - options on command line override config options - removed tap and http files which are not used anymore - changed directory structure to put source in src, to be coherent with SàT and Libervia - changed options name, db* become db_*, secret become xmpp_pwd - an exception is raised if jid or xmpp_pwd is are not configured
