Cleaner header construction with the field_init_shorthand feature

The field_init_shorthand unstable feature can probably help you get a cleaner header construction.

Ho ! Sorry, you want only stable Rust. We will probably wait this feature to be added into stable releases.

[bluejekyll]

Yes, and that's some of my oldest Rust code. Could definitely use some touch ups...

Rust 1.17 was released and it supports the field init shortcut syntax now.

BTW, I saw the comment in the code about using the builder pattern. I agree that the current, non-builder, way is better.

[bluejekyll]

Yeah, I just saw that today. That will be really nice. If anyone wants to submit a PR for this, that would be great. Otherwise, I'll start cleaning some of this up as I come across it.

fixed in #179
