Reviewed by Alex Christensen.

Embedded objects in Mail signatures were broken when the
plugins-enabled preference was effectively removed.

This patch adds a quirk triggered on
[WebPreferences setPlugInsEnabled:YES], which then lets
FrameLoader::SubframeLoader::requestPlugin continue
handling the plugin-like objects in Mail signatures.
