Add a setting to ignore hash checks

[hyenaheartbeats]

Goal

Fix errors related to incorrect zlib outputs.

Motivation

Some distributions of linux use zlib-ng rather than zlib itself with no option to use regular zlib; many of the bug reports about the error "Processor failed, invalid outputs" are due to hash checks failing because the launcher expects the outputs from regular zlib. I currently cannot run modpacks exported from other OSes on Fedora.

The FeedTheBeast launcher already has this setting.

Specification

Add an option to skip hash checks.

The launcher itself does not handle Forge. I wonder what's going on in FTB Launcher...
Also I believe the Forge checksums are meant to be ignored in all cases

this exists in newer versions of prism ForgeWrapper. Just add -Dforgewrapper.skipHashCheck=true to your java arguments
