Detect home server from matrix id

Added functionnality :

• you can now enter the user matrix id (e.g. @username:server.local) in the login input.
• if the home server that you've entered into youre id is not the same that those into the home server input, it will be use instead to connect to the default matrix server.

Should fix this issue (#479).
