the library is no longer compatible with the stable compiler

[joseluis]

I noticed it since I only use the stable compiler and I was surprised by the undocumented breaking change.

After the following changes the library doesn't compile in stable anymore:

bsv-wasm/Cargo.toml

Line 15 in 67ce940

wasm-bindgen = { version = "^0.2", features = ["serde-serialize", "nightly"] }

bsv-wasm/src/lib.rs

Line 1 in 67ce940

#![feature(trait_alias)]

I personally don't think removing stable compatibility is a good idea, specially not just to avoid using an ugly long chain of traits in only 3 places...

For now I've removed the feature and the trait alias definition in my local copy in order to be able to keep working with this lib...

Great point, I actually didn't consider how changing the builds to nightly would impact the usage of the library when other people are using it in Rust. I'll fix that up now.

@Firaenix I found the trait-set crate that would allow if you want to recreate the trait aliases removed in #39, in stable Rust.
