Request: Add a filter for the code before it gets parsed

Hi,

Nice plugin.

I’m wondering if you can add a filter for the code string right before it is gets parsed.

Case in point, I would suggest something like this.

On line 221,

function code($code = NULL) {
		if ($code === NULL) {
			return $this->code;
		} else {

			// Trim whitespace
			if ($this->setting_val(CrayonSettings::TRIM_WHITESPACE)) {
				$code = preg_replace("#(?:^\\s*\\r?\\n)|(?:\\r?\\n\\s*$)#", '', $code);
			}

Change it to

function code($code = NULL) {
		if ($code === NULL) {
			return $this->code;
		} else {

			$code = apply_filters( 'crayon_highlighter_pre_code_format', $code );

			// Trim whitespace
			if ($this->setting_val(CrayonSettings::TRIM_WHITESPACE)) {
				$code = preg_replace("#(?:^\\s*\\r?\\n)|(?:\\r?\\n\\s*$)#", '', $code);
			}

The filter name can be whatever suitable.

This way, I can customize the behaviour of the plugin without editing the plugin code. I need to strip and replace some parts of the text before it gets parsed which are inserted automatically by my blog writer(text editor).

Thanks for your consideration.
