Also fixed an issue w.r.t the plugin architecture. Previously infinite
recursion would happen when more than one plugin was overriding a method.
Resolved now by using a wrapper function that lazily sets the correct super
method.
The __ translate method should only be run *after* converse.js has been
initialized and we know what the actual desired language is
Also fix bug in src/locales.js where wrong langs were assigned to wrong keys.
- converse-muc.js was overriding the global "converse" variable
with undefind (the factory function didn't return anything)
- locales was not defined in utils.js in non AMD (not passed in
the factory function)
First component to remove is MUC which was moved to src/converse-muc.js
The components are written as plugins and use converse.js's plugin machinery.
Update the plugin docs somewhat with new insites found while working on the muc
plugin.
