[Cctools-cchost] Added support cc button to default cchost

[Jon P. <jo...@cr...>]

Heya, I added the support button to the default ccHost install as a
sidebar option so that any installations can turn this on and a lovely
button shows up.

Also, please note that anyone who does this can be be linked to from the
cc support section:

Cool!

Jon (more lame hacks from me)
