Have proper autocompletion for /software in chat window

In console autocomplete from roster.
In muc autocomplete from occupants lits.
In 1:1 regular chat autocomplete from active resources of currently
selected user (new).

Also give a hint (/help resource) how to set the resource should a user choose that way.
