Update mongrel to version 1.1.4.  Changes from version 1.0.1 include:

+ Remove dependencies on cgi_multipart_eof_fix and fastthread because
  newer versions of Ruby required by pkgsrc don't need it.  Also remove
  signatures from the gem as these have been modified by pkgsrc.

v1.0.3. Fix user-switching bug.
v1.0.4. Backport fixes for versioning inconsistency, mongrel_rails bug,
and DirHandler bug.

v1.1.2. Fix worker termination bug; fix JRuby 1.0.3 load order issue;
