mime-types ~> 1.16 dependency

gem install veewee fails as Fog install mime-types 2.0, but Grit requires ~>1.15.  Fog requires ~>1.16, so we can make everyone happy with a ~>1.16 dependency.

mime-types ~> 1.16 dependency
Order of s.add_dependency is important

if s.add_dependency "mime-types", "~> 1.16" is specified below fog, gem considers fog first and its requirement on mime-types > 0, pulls in mime-types 2.0.  I gave gem too much credit for calculating dependencies ordering, it does _not_ do that at all.
Merge pull request #877 from braddeicide/master

Order of add_dependency is important, mail-types must come before fog.
