[GUI] Update of the opinion poll document.

I tried to summarize the recent discussions on this list in the technical section. The easiest way to read it is to use the following link: http://www.cs.ukc.ac.uk/people/staff/as49/poll.pdf The document is now available under /home/cvs/root/haskell-report/gui/poll.tex in the (GHC) CVS repository on haskell.org. The only way to receive emails about commits seems to be to subscribe to cvs-all which probably fills you inbox quite quickly. Thus I recommend: if you make bigger changes (and any change is welcome), just write a message to this list. Lacking is a statement about procedure (naming versions "Proposal", "Stable", etc). I'll add that some time in the future. Axel.
