Facebook (and other) XMPP workaround

[Krzysiek G]

Hello,

Some time ago Facebook remove groups support in XMPP
 https://developers.facebook.com/bugs/285769454799737
There is also similar problem with other sosial network

Currently it is no problem but it will be with metacontacts and local
contact storage.
I have idea of workaround.
What do you think to add option to ignore group name (ignoring name
could be also useful) when syncing data from server.
Option per account or per protocol.

Greetings
