Remove MSYS2 CMD Shell extensions in favor of separate MSystem project

[userzimmermann]

The included .bat scripts for managing and using MSYS2 directly in a CMD Shell are outdated and continued in my separate MSystem project:
https://github.com/zimmermanncode/MSystem

I will remove those old scripts before making a new Chocolatey MSYS2 release.

If there is no harm in publishing an updated version to chocolatey, could I ask that you do that, and then this? I'd love to get a new version, since my bazel package has taken a dependency on msys2, and so that's blocked until there's a version that installs cleanly within the chocolatey automated validation check.

FWIW, I'm manually building the msys2 package at https://github.com/rgl/visual-studio-community-vagrant/blob/master/provision.ps1#L292 (which is now kinda broken since the @petemounce branch that I was using does not exist anymore, but changing to the master branch of @userzimmermann works fine).

[petemounce]

@rgl sorry about that; I deleted it once it was merged. I'm a fork, not the canonical; it didn't occur to me that someone might have taken a dependency on me.

[rgl]

@petemounce ah no worries! I knew that it would eventually happen once your pull request was accepted :-)

[petemounce]

@userzimmermann thinking about it - would it be possible to choco push each of the versions of msys2 that have happened since #3 was merged, so that users with a dependency on a particular release have those to choose from?

If it's a question of having time, if you'd be willing to allow me access to push the built package, I'd be more than willing to help.

@petemounce Hi. I think so too. We should push all those versions starting from 20160719.0.1. The removal of the CMD shell stuff can wait ;) And yes, let's manage that package together on chocolatey.org! I will only make the same little change to the included msystem.bat for 20160719.0.1 like in 0a89c68 in a new separate msys2-20160719 branch and create the first release from there:
https://github.com/userzimmermann/choco-packages/commits/msys2-20160719
I have some more work to do now... let's continue this evening :)

@rgl Nice that you still use my package and everything works fine again :)

[petemounce]

@userzimmermann thanks! On chocolatey.org, my username is petemounce as well.

[userzimmermann]

@petemounce @rgl BTW: I also upload my choco packages to https://www.myget.org/gallery/zimmermann-choco
Which might be easier to use as long as new packages on chocolatey.org are not approved yet.

And I also have my own CI tests for the msys2 package at https://ci.appveyor.com/project/userzimmermann/choco-packages-6hb62

[userzimmermann]

Officially released 20160719.1.0

@petemounce And I added you as msys2 maintainer on chotolatey.org

[majkinetor]

I created a new version , please take a look:

chocolatey-community/chocolatey-packages#891

[userzimmermann]

@majkinetor Nice! I should have reacted much earlier to all those requests regarding my msys2 package... Just too many projects ;)

[userzimmermann]

@majkinetor The work on my extensions also only very slowly progressed... But it's going on again now :) So I will release them separately with your new pure msys2 package as dependency soon
