[PATCH] Remove excess elements from Atom 1.0 feeds

Hello,

Please find attached the patch.

[[
Patch by: Bhuvaneswaran Arumugam <bhuvan@collab.net>

Insert the "entry" element before all other "entry" elements and remove
the elements from the feed file if it reaches --max-items.

* contrib/hook-scripts/svn2feed.py
  (Svn2Atom.add_revision_item): Locate the "author" element (last
  non-entry element) and insert the new element after it's next sibling.

  Calculate the total "entry" elements and remove the last child if the
  total is greater than the --max-items.
]]

Design: Locate the "author" element (last non-entry element) and insert
the "entry" element before its next sibling. I'm unsure if it is the
efficient way, but feel free to change if you find a better way.
