Hello,

this patch implements sticky article buffers. With `C-c s' in Summary
Buffer you open an article buffer and make it sticky. Sticky means that
it won't be killed when selecting another article or leaving the
summary.

This might me useful if you write an article and have to quote many
other articles (which you would make sticky first, instead of visiting
them via summary over and over again).

You kill a sticky article buffer with `q' in it or with
`gnus-kill-all-sticky-article-buffers'.
