clix.raw: Add a shorthand for top level stanza attributes

The m, p and iq functions are amended so that indexing them sets the
'type' attribute and a subsequent function call with a string sets the
'to' attribute.

Examples:

m.chat"recipient":body"Hello"

iq.get"example.com":query"jabber:iq:version"
