Show help if no argument is provided
In case someone calls `xmppc` assume that he doesn't know how to use it.
Which means he might even not be aware of `-h`.
So let's print the help in case no argument is provided instead of
connecting, then discoverin that no mode is selected and disconnecting
again.
Fix segfault when not roster subcommand is provided
_roster_parse_command() segfaults since it assumes there is an argv[0].
Let's test the number of arguments.
Since we are already connected xmpp_connect_client() will wait for a
disconnect. So I introduce a teardown function that is called in both
the error case and the succesful case.
Now _roster_send_query() doesn't disconnect anymore.
Set to development by default
Only set to release when a new release is tagged.
Like this not every developer needs to change the code.
And it's git aka development anyways.
