Stray DSL note reference in style/naming-conventions.md

[rduplain]

It's minor, but apparently there is a domain-specific language note to reference in the Parentheses section of the Naming Conventions doc:

Methods which act as accessors of any sort (either encapsulating a field
or a logical property) should be declared *without* parentheses except
if they have side effects. While Ruby and Lift use a `!` to indicate
this, the usage of parens is preferred [\#dsl\_note]\_.

I cannot trace down what doc is supposed to be linked here.

Hey, thanks a lot for pointing this out. I'm actually not sure where that reference originally pointed to-- @davetron5000 do you know where that might have originally pointed to? (Doesn't seem like too much of a loss if I just remove the reference.)

It linked to a footnote that had the following text:

[1] Please note that fluid APIs and internal domain-specific languages have a tendency to break the guidelines given below for the sake of syntax. Such exceptions should not be considered a violation so much as a time when these rules do not apply. In a DSL, syntax should be paramount over convention.

Since Markdown doesn't support footnotes, we could probably just add it as a parenthetical expression?

Here's a stab at it: https://github.com/davetron5000/scala.github.com/tree/add-dsl-footnote

Seems perfectly fine to me. Thanks for clearing it up!
