Speed up the JavaScript syntax highlighter by generating the finders only once

[Timothy Hatcher]

The syntax highlighter can be speed up more by generating the finders only once when syntaxHighlightJavascript is called, not per line.

Proposed patch (ignoring whitespace changes)

+        Removed, factoeed into syntaxHighlightJavascript as an inline function.

Typo: factoeed

-        var findSingleLineString = generateFinder(/^"(?:[^"\\]|\\.)*"|^'([^'\\]|\\.)*'/, 0, "webkit-javascript-string");
+        var findSingleLineString = generateFinder(/^"(?:[^"\\]|\\.)*"|^'([^'\\]|\\.)*'/, 0, "webkit-javascript-string"); // "

Why this change?

Needed to keep Xcode's syntax highlighting sane. I added some words to that comment.
