Gitweb: add support for Alex Gorbatchev's SyntaxHighlighter in Javascript

Browse source 
Gitweb is not exactly what you would call server-friendly, so let's
offload one more task onto the client.

To enable this, put something like this into your gitweb_config.perl:

	$feature{'syntaxhighlighter_js'}{'default'} = [{
		url => '/SyntaxHighlighter/',
		style => 'Django',
		theme => 'FadeToGrey'
	}];

and clone git://github.com/alexgorbatchev/SyntaxHighlighter into the
directory you specified via the 'url' parameter.
