• Increased Perl version requirement to 5.16.0. This is just a first step however, at some point in the not so distant
  future we will increase the Perl version requirement to 5.20.0 for full subroutine signatures support.
  
• Improved Mojo::Base to enable the Perl 5.16 feature bundle with "unicode_strings", "unicode_eval", "evalbytes",
  "current_sub" and "fc".
