imap.el: Revert back to version cb950ed8ff3e0f40dac437a51b269166f9ffb60d, since some of the changes seem problematic.

Fix up the w3m/curl dependencies.
mm-decode.el (mm-text-html-renderer): Don't have gnus-article-html depend on curl, which isn't essential.
gnus-html.el (gnus-html-schedule-image-fetching, gnus-html-prefetch-images): Check for curl before using it.
