Respect TM_ZIG environment variable

The argument passed to require_cmd did not respect the TM_ZIG
environment variable.

@emekoi would you mind taking a look at this one, #52 and #53? Further, I would be happy assist in maintaining this bundle. I'm already doing something similar for the Crystal TextMate bundle. 🙂

@kevinsjoberg i see we now have https://github.com/ziglang/Zig.tmbundle. is the plan split the TextMate and Sublime Text stuff? since it seems you are already helping out with TextMate library, i would be glad to have you.

[hovsater]

Yeah, we split yesterday and I'll maintain the TextMate version. 🙂

so is the plan to have github's lignuist continue to point here, or will it point at the TextMate version? also i suppose this means i could remove all the TextMate-specific stuff from this repo and vice versa for the TextMate one. i have no real preference as to whether that happens though.

[hovsater]

I think we can keep Linguist pointing here still. I've already updated the README in the other repo.

Feel free to remove TextMate specifics. 🙂

[emekoi]

the issue is that linguist relies on TextMate syntax files, but the newer sublime text syntax features aren't compatible with them iiirc.

[hovsater]

Oh, in that case I think it makes sense to keep it in the TextMate bundle. I'll submit a PR to linguist itself to change the repo. 👍
