* Modify version constraints to be an Array
This will allow both old and new versions of InSpec to parse the
`inspec.lock` correctly.

When configuring a profile dependency, if the dependent profile had a
hyphen in it, it would not properly match the default version constraint
of `>= 0`. This is because a hyphen indicates the version is a pre-release
version and proper version matching would require the constraint to also
be listed with a pre-release version string.
The proper solution is to use the `+` character instead which indicates
a build number, which is what the hyphen was meant to convey. In the
meantime, this change properly compares version strings as SemVer and
also adds tests.
