Returns a hash representing the version of Sass.
 The `:major`, `:minor`, and `:teeny` keys have their respective numbers as Integers.
 The `:name` key has the name of the version.
 The `:string` key contains a human-readable string representation of the version.
 The `:number` key is the major, minor, and teeny keys separated by periods.
 The `:date` key, which is not guaranteed to be defined, is the `DateTime`
   at which this release was cut.
 If Sass is checked out from Git, the `:rev` key will have the revision hash.
 For example:

     {
       :string => "2.1.0.9616393",
       :rev    => "9616393b8924ef36639c7e82aa88a51a24d16949",
       :number => "2.1.0",
       :date   => DateTime.parse("Apr 30 13:52:01 2009 -0700"),
       :major  => 2, :minor => 1, :teeny => 0
     }

 If a prerelease version of Sass is being used,
 the `:string` and `:number` fields will reflect the full version
 (e.g. `"2.2.beta.1"`), and the `:teeny` field will be `-1`.
 A `:prerelease` key will contain the name of the prerelease (e.g. `"beta"`),
 and a `:prerelease_number` key will contain the rerelease number.
 For example:

     {
       :string => "3.0.beta.1",
       :number => "3.0.beta.1",
       :date   => DateTime.parse("Mar 31 00:38:04 2010 -0700"),
       :major => 3, :minor => 0, :teeny => -1,
       :prerelease => "beta",
       :prerelease_number => 1
     }
