The package was broken as it used an always up-to-date URL, having
spoken to peterix (the developer of the launcher at mojang) - they
have no plans to have versioned URLs exist for Windows.
[6:04 PM] peterix: no, and there will be no such thing
[6:05 PM] peterix: the launcher doesn't need packaging on windows
[6:05 PM] peterix: plus, there would be no point in doing that,
because it immediately updates
...
[6:22 PM] peterix: that is not an official source of the launcher
[6:22 PM] peterix: and it shouldn't be there
[6:22 PM] peterix: under any circumstances
Therefore, as it will not be possible to maintain this package, this
commit removes it.
