lhchavez b78bde3d74 Make all Options objects consistent
This change makes all Options objects have child Option fields as values
(instead of pointers) to mirror the libgit2 interface. It also names
them Options instead of Opts to match the current libgit2 nomenclature
and removes the Version fields.
