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`.
Replace :hwvirtext with :hwvirtex

`:hwvirtext` isn't an attribute accepted by `modifyvm`.
Remove rel_path causes issues on windows across drives.

Given
	PWD is z:/src/gendev
	RUBY is installed in C:/Ruby193
	path1  = veewee/iso/sol-10-u11-ga-x86-dvd.iso
	path2  = Z:/src/gendev

When
	I run veewee vbox build <definition>
Then
	 I get the following error.

	C:/Ruby193/lib/ruby/1.9.1/pathname.rb:465:in `relative_path_from': different prefix: "" and "Z:/src/gendev" (ArgumentError)
	        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/veewee-0.3.12/lib/veewee/provider/core/helper/iso.rb:116:in `verify_iso'
	        from C:/Ruby193/lib/ruby/gems/1.9.1/gems/veewee-0.3.12/lib/veewee/provider/core/box/build.rb:37:in `build'

Since both a relative and absolute paths should work with curl, md5, and shasum there should be a need to validate a relative path to the iso.

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.
