Bug #117394 for WWW-Mechanize-CGI: Patch for erratic error info passing bug.

Hello to whomever maintains this module, Attached is a patch to fix a bug whereby the error caught and held in $@ is only sometimes being returned in the 'X-Error' custom header. Said bug is due to the code which assigns $@ to the $error variable being too far away from where $@ is set (it is set upon failing an eval block; the assignment to $error is several statements away and outside the block where $@ was originally set -- so plenty of time and/or opportunities for $@ to be munged). This patch also includes documentation for the currently undocumented use of the 'X-Error' custom header. This patch is being released under the same licsense as WWW::Mechanize::CGI itself (so, to make this explicit: this patch is licsensed under the same terms as the Perl 5 programming language system itself).
