Linux install constantly prompts for "install in path about cli

@enygren obviously there's a bug here!

1. Would you be able to share the path you have it installed in vs your PATH, so we can see why it doesn't think it matches. I suspect it's because you installed it to non-user-writeable path in PATH, and I excluded those from the list of potential places. Will double check this and update the logic.
2. A suppression mechanism would be good, what do you think of limiting it to the current version only?
3. Absolutely it shouldn't prompt when stdin/out aren't TTYs, I'll double check on that.

@enygren I believe I was correct about this, and have fixes in for (1) and (3) above, they will be in the next release.

I'm also working on a more comprehensive configuration file that can store information like that needed for (2), which may or may not make the next release.

I'll update this issue when those fixes go out.

This issue will be fixed in the 0.5.0 release.
