Bump Ruby version to 1.9.3

OS X 10.8 doesn't have a build, and for some reason RVM doesn't want to build it from source:

	$ rvm install ruby-1.9.2-p320
	No binary rubies available for: osx/10.8/x86_64/ruby-1.9.2-p320.
	Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
	The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`.

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.

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