update to require digest/md5 instead of md5

[steveroot]

s3sync didn't work for me giving error of:
home/sroot/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in require': cannot load such file -- md5 (LoadError)

It appears ruby 1.9 uses digest/md5 instead of md5
I suggest someone more knowledgeable checks this before accepting the pull request.

I can confirm that ruby 1.9.3 uses digest/md5.

:~ chris$ irb
1.9.3p194 :001 > require 'md5'
LoadError: cannot load such file -- md5
    from /Users/chris/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /Users/chris/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'

    from /Users/chris/.rvm/rubies/ruby-1.9.3-p194/bin/irb:16:in `<main>'
1.9.3p194 :002 > require 'digest/md5'
 => true 
1.9.3p194 :003 > 

I can also confirm that changing "require 'md5'" to "require digest/md5" on line 23 of s3sync.rb will fix the error

+1 for me, is this gem no longer maintained?

There are 2 forks that I know of that have fixed this issue: aproxacs-s3sync and frahugo-s3sync.
