[Conkeror] xkcd-mode change

[John J Foerch]

Hi all,

  I made a change to xkcd-mode such that it does not insert the caption
of the comic into the web page by default anymore.  To enable that
feature, put the following in your rc:

   xkcd_add_title = true;

  This change was made in recognition of a reasonable expectation that
in its default configuration, conkeror should show all web pages as
intended by their authors.  Xkcd-mode also provides another feature,
patterns for "[[" and "]]" to assist in navigating xkcd.  Since that
feature is a non-breaking "strict improvement" to conkeror, it seemed
best to keep xkcd-mode as one of the default page-modes, but to require
users to explicitly enable its content-editing feature if they want it.

  Sorry for the inconvenience.
