selectors: replace comma whitespace with comma enter. And alphabetize them correctly

[RedDragonWebDesign]

Add both these code snippets as tests, too. Make sure coming in with comma enter already doesn't break anything.

Before:

#menu-main > li > ul > li > a, #menu-main > li > a {
	color: white;
	display: block;
	padding: 18px 25px;
	text-decoration: none;
}

After:

#menu-main > li > a,
#menu-main > li > ul > li > a {
	color: white;
	display: block;
	padding: 18px 25px;
	text-decoration: none;
}
