align with spec requirements, meaning no leading zeroes on semVers

[baronfel]

per the spec:

A normal version number MUST take the form X.Y.Z where X, Y, and Z are non-negative integers, and MUST NOT contain leading zeroes. X is the major version, Y is the minor version, and Z is the patch version. Each element MUST increase numerically. For instance: 1.9.0 -> 1.10.0 -> 1.11.0.

Emphasis mine

Actually found this when I was integrating this module into FAKE, thanks to the tests over there.

Build is red. Can you please check

Note that 0 starts with 0 as well, and 0.1.0 is a perfectly valid version number.

We also need to support 0 itself since it is used in “=> 0" all over the place Am 08.05.2017 8:28 vorm. schrieb "Christoph Ruegg" <notifications@github.com

ok this is looking fixed up now. I'm super curious what it would take to move us over to SemVer.net instead of a home grown parse, and it looks like we mostly have a

1. semi-convention around the 'name' of the prerelease segment being the first alpha segment,
2. various tostring functions that normalize for nuget (which may not be necessary anymore if the 3.4+ documentation is correct in that they strip leading zeroes, and trailing 4th segment zeroes)

[forki]

@baronfel the issue is always to support old released nupkg that don't conform to semver

[forki]

we recently made paket more conform to semver. So hope it's better now.
