Switch to SemVer

[awickham10]

Can we switch the version numbering to SemVer format (x.y.z)? We run a NuGet gallery on-premise and it expects everything to be SemVer. We're seeing an issue where Get-Module won't find it if it's pushed to NuGet, which forces SemVer.

I totally forgot about this until now. I'll see if I can get to this tomorrow.
