[IPython-dev] Magics that have return values, $$var=cmd simplification

I figured we could implement a handy and intuitive way to grab
both magic return values and system command output:

var = %mymagic args a plenty

var = !command args a plenty

The regexp to catch these reliably is trivial (provided that var name
is (\w+) and both are illegal python. Anyone have any
doubt/objections? $$var = cmd syntax is there but it's not as easy to
remember or obvious.
