Style Elixir function parameter variables

[rgreenjr]

Description of the Change

Support for capturing function parameter variables was recently added to the Atom Elixir syntax. This pull request uses these new captures to style Elixir function parameter variables. It sets their font style to italic and color to @hue-6. This matches the styling used by Sublime Text and TextMate.

Here's before:

And here's after:

Alternate Designs

None

Benefits

Elixir supports function pattern matching. This change makes it easier to differentiate function parameter variables from other function parameters. See the image above for several examples.

Both Sublime Text and TextMate apply a similar styling to Elixir function parameter variables.

Possible Drawbacks

None

Applicable Issues

None

Sorry about that @rgreenjr - the person who might normally review this is OoO for a while. I can't make any promises, but I'll mention this to the team for you.

If it's not too much trouble, could you add a "before" image to your issue body?

[rgreenjr]

Hi @rsese, thanks for the quick reply.

I realized after I posted my message that I probably should have posted a "before" image to make reviewing the changes easier. Sorry about that, I'll update the issue body right now.

Thanks again.

np thanks for adding the before image @rgreenjr :bow:

I asked the team about your PR and we agreed that it's best if @simurai takes a look when he gets back.

/cc @simurai to get this on your list :v:
