Requests fail with NotSupported, depending on $TERM

[Kha]

I can reproduce iron/logger#79, even with 007aa62:

$ TERM=dumb cargo test

ugh. That library has a lot of problems for something that writes to stdout. Probably time to write something simpler around println!.

Thanks for the report!

[Kha]

I feel like I'm doing something wrong (if it wasn't a single cargo test), because I can still reproduce this on 4b8d3c7 😆 .

[jwilm]

What! Ugh. Need to drop that dependency.

[micbou]

@jwilm Do you plan to drop the logger dependency or update it as in PR #63? Some of our users are experiencing the issue. See ycm-core/ycmd#849.

[msanders]

^ I'm running into this issue as well when using racerd with emacs-ycmd. Updating the logger dependency as in PR #63 seems to fix it.
