Rustup to rustc 1.12.0-nightly (1225e122f 2016-07-30) and bump to 0.0.80

[mcarton]

Yup, there's been another problem after #1119.
Fix #1120.
Ref rust-lang/rust#35090.

Argh, Travis is always picking rustc 1.12.0-nightly (f164cf5 2016-07-29), I'll try again later.

[mcarton]

Well, Travis still won't cooperate and I'm off for the week.
@Manishearth, @oli-obk , @llogiq, @birkenfeld: Can one of you publish the crates? 😄

(>10h cache for a nightly seems excessively long 😕)

[Manishearth]

Will do 😄

[oli-obk]

error: api errors: crate name has already been claimed by another user

huh.. cargo publish doesn't like me, I'll go read some cargo docs

[oli-obk]

oh oh... only @mcarton owns the clippy_lints package... This means that ever since the split only @mcarton has published the crates xD tips hat

[Manishearth]

@mcarton could you cargo owner -a Manishearth and cargo owner -a oli-obk in the clippy_lints folder? (I'll add the rest)

I've pinged Alex to see if he can manually add me as an owner so that we don't have to wait for your vacation to get over 😄

[Manishearth]

Alex helpfully gave me access. Published, and added owners.

[mcarton]

oh oh... only @mcarton owns the clippy_lints package...

Oops, did not realize that 😄

Thanks to Alex!
