MSBuild team is changing "{major}.0" to "Current" to make VS2019 and newer easier to automate in devops via vswhere.

microsoft/vswhere#162 (comment)

Any thoughts about the permanent solution?
The following works so far, but from the vswhere discussion, a better should be done

@gerhardol Here's src for this part, you can use PR: https://github.com/3F/hMSBuild/blob/master/frontend.bat#L522

About solution, what about future 17+ VS releases ? :)

I think GEQ operator is enough.

Also, I don't know more details about an "Current" naming, but just to be sure ( #3 (comment) ) probably we also need to check this dir like ~

if !vsver! GEQ 16 if exist "!thisDir!" (
	set vsver=Current
)

or maybe not ... well you can open PR, I will look into later.

Please also test the new solution in real usage. Thanks!
use build.bat for manual compile for your PC, or see CI appveyor
