Elixir language support

[arcticicestudio]

Implement optimized Elixir styles for the milestone backlog community 📦 package language-elixir by elixir-lang

1. Use annotation color for .module CSS class and the associated punctuation definition symbol
2. Use class color for .constant CSS class

Requested by @skbolton in the backlog milestone issue.

[arcticicestudio]

@skbolton These are the style optimizations I've implemented so far.
You can test it by installing the language-elixir package and check out the ghi-#33-elixir-language-support branch.

Feel free to suggest improvements/additions 😄 🎅

Will definitely play with it over the holiday break. I love that color for the annotations, I was going to use the same one from the color palette. Really nice

[skbolton]

Yeah I really like the addition of the rust color for annotations. Now I just wish I could get more of that color in my js highlighting :)

[arcticicestudio]

I'll merge this and prepare a new release version in the next days.
Do you mean ES6 decorators like @readonly?
