[gclist] FAQ update

[chase@centerline.com]

I added a chunk of GC-in-C/C++ evangelism.  I'm moderately embarrassed,
because it reads sort of like a marketing brochure (I flatter myself,
I'm sure it reads like it's condescending, which is not good).

Anyhow, it's there, give it a look, try:

That earlier message from me was a mis-sent party RSVP, in case
any of you were wondering.  I got more replies from that than I have
from any "have-a-look-at-the-FAQ-what-do-you-think" requests.
