RFS: ruby-nokogiri

Hi!

I've updated ruby-nokogiri repository to a newer version. It is lintian
clean and builds fine with cowbuilder.
Here is the changelog entry for this new version.

ruby-nokogiri (1.5.2-1) unstable; urgency=low

  * New upstream version
  * Add myself to Uploaders:
  * Bump Standards-Version to 3.9.3 (no changes needed)
  * Exclude temporarily test_xinclude.rb from the tests, as xinclude.xml is
    missing in this version
  * Add fix-sporadically-failing-tests.patch (Closes: #661690)
  * Set Priority: to extra for transitional packages
  * Override lintian warnings about duplicate decription for transitional
    packages
  * Convert copyright file to DEP-5
  * Provide a simple manpage for nokogiri binary

much in advance.

Best wishes,
