Sort semantic versions

Sort version strings by Semantic Versioning 2.0 precedence, lowest first. Each version is MAJOR.MINOR.PATCH (non-negative integers), optionally followed by "-" and a pre-release (dot-separated identifiers of letters, digits and hyphens) and then optionally "+" and build metadata.

Rules: compare major, minor and patch numerically. A version with a pre-release is lower than the same version without one. Pre-releases are compared identifier by identifier from the left: identifiers of only digits compare numerically, others compare in ASCII order, numeric identifiers are lower than non-numeric ones, and if all shared identifiers are equal the shorter list is lower. Build metadata is ignored; versions of equal precedence keep their input order.
