Hi,

Looks like the recent monkey patching of ZipEntrySet to sort zip file
entries is causing some important performance regression... The combined
rubyzip+patch algorithm is O(N^2) so zipping 1200 entries now consume 100%
of my CPU for 20-30 seconds...

New version in SVN should be faster (or more precisely, only use sort once).
