re-generated muc plugin
created a bower.json file to permit use with bower package manager
fix a bug in strophe.roster plugin, it would have broken the connect function if we were needing a 'route' parameter in our connect function, as the plugin is overriding the connect function, but was not handling that 'route' parameter
updated bower package to version 0.0.2
Merge branch 'master' of github.com:allan-simon/strophejs-plugins into fix_roster_plugin_connect_bug
