Add syntax highlighting to structs to be like other types. (#70)

* Add syntax highlighting to structs to be like other types.

The code looks more unified and easier to look at instead of situations like below.

void function(orange, orange, yellow, orange)

or

(orange) char = "string";
(yellow) struct;
(orange) float = 5;

* Removed space I added on accident.
