ejabberd: Document how to connect using Jabber clients

Ejabberd is an instant messaging server that FreedomBox provides. Once this service is setup, a user needs to install and configure a client application to connection to the XMPP/Jabber instance network. Providing the details for configuring the clients involves providing many details about the server. It can be overwhelming to new users. Document the process of connecting to ejabberd server from Jabber clients in the FreedomBox Manual. The FreedomBox Manual is a wiki page hosted on https://wiki.debian.org. Page to be edited is https://wiki.debian.org/FreedomBox/Manual/ejabberd

• In Ejabberd manual page for FreedomBox, write a section about configuring Xabber app on Android to connect to FreedomBox server with screenshots.
• In Ejabberd manual page for FreedomBox, write a section about configuring Gajim app on GNU/Linux to connect to FreedomBox server with screenshosts.
• In the configuration instructions, the domain name used should not be an IP address but a real-world domain name such as myserver.freedombox.rocks.
