Feature Request: Allow Parameters to Pass to mintty

[AntumDeluge]

I would like to be able to pass --tabbar to mintty from the launcher. Currently it doesn't appear possible to do so. So I edited launcher.c & added it to the command string. An option to pass custom parameters would be helpful I think.

I think I already talked about this elsewhere, but the blocker (at least in my head) for such a feature is the command line parsing. I'm really trying to avoid having any arguments to the launcher itself in order to keep the parsing simple. I'll try to think about it.

I must have forgotten about this, because I'm pretty sure I was able to do what I was requesting here. But it has been a while since I used MSYS2, so I don't remember how off the top of my head. I'll look it up when I get back on my Windows machine.
