[RP] new fdump structure may affect scripts

[Shawn Betts]

Hi folks,

I changed the fdump format from a list of numbers to an sexpr:

(frame :number 1 :x 2 :y 3 :width 5 :height 6 :window 24595 :last-access 5 
:dedicated 1)

This makes it more humanly readable. And it allows new slots to be
added without extra parsing (if you've written a smart parser). Plus
you can drop slots you're not interested in:

(frame :number 1 :x 2 :y 3 :width 5 :height 6 :last-access 5)

and it still works.

Comments?
