Can't use async-std on beta channel

[ChrisGreenaway]

When I add async-std as a dependency and try to compile with the beta channel I get:

error[E0554]: `#![feature]` may not be used on the beta release channel
  --> /home/chris/.cargo/registry/src/github.com-1ecc6299db9ec823/async-std-0.99.3/src/lib.rs:30:1
   |
30 | #![feature(async_await)]
   | ^^^^^^^^^^^^^^^^^^^^^^^^

#![feature may not be used on the beta release channel clearly says why you can't use nightly features using beta channel. Use nightly.

async/await is stabilized now, so this could be solved by removing the #![feature] line.

async/await is stabilized now

This is starting tomorrow's nightly, and requires landing + releasing #94 first. Getting real close but not quite there yet!

async-std can't be used on the beta channel until September 26th, when the next beta is cut, as all other async/await crates.

Closing this, as relevant features for async-std have not hit beta yet.
