Once #717 is merged, how about introducing GlobalSettings.Version?

This would be a type exposing several properties

• Version MinorMajorPatch { get; }
• Features BuiltInFeatures { get; }
• string LibGit2CommitSha { get; }
• string LibGit2SharpCommitSha { get; }
• string CpuArchitecture { get; }

The ToString() method would be overriden to produce what Repository.Version outputs nowadays.

Repository.Version would be deprecated in favor of this new type.

Thoughts?
