Fix Highlighting of 'include' and customizer

[Antyos]

Includes

The keywords, include and use could have better looking coloring. Color inside the brackets should maybe match the brackets?

include <file.scad>;
use <file.scad>;

Example:

Customizer

Comments are highlighted where they shouldn't be.

Example:

Methods / Functions

Capture group is messed up when searching for functions if the parentheses aren't included.

Example:

Also, incorrect names, such as function foo//() do not highlight correctly.
