Hide account in roster if there is only one

[beerfan]

There seems little reason to display the account in the roster if the user only has a single account. The account encryption status is displayed here but that could easily be moved into the account management window (show the connection status and type in extra columns) as the encryption method is not likely to change often if ever.

I disagree with that, account line handle many things. Like what you said

but also our own message status and priority (in tooltip), and possibility to send a single message. Try to reduce account font size in theme.

we used to do this, but as im says we show many info
