#![feature(custom_attribute)] prevents compilation on stable

[Electron100]

This package cannot compile on stable Rust due to the use of #![feature(custom_attribute)] . It's unclear (to my anyway) why this feature is specified. If it is removed, the package compiles without issue on stable (1.32)

Based on the latest discussion at rust-lang/rust#29642, it appears that the custom_attribute feature is likely to be removed from nightly soon, anyway.

Good catch. I copied the feature flag out of an older project that been started back when #![feature(custom_attribute)] was necessary for wasm_bindgen, but it looks like that's no longer the case.

This should be fixed with the latest release. Thanks for reporting the issue!
