Found 2 bugs

First of all I think this is a great plugin!

I found two bugs tough, and no other way to contact you than through this support forum. So here they are:

1. Softlinks does not work when inserting media. This is because the $search array on line 120 has errors:

$search = array(
	'src=""',
	'href=""'
);

should be:

$search = array(
	'src="',
	'href="'
);

I worked around the above problem with my own filter, but it would be nice to not have to do that 🙂

2. When the page content is empty, wp softlinks throws a warning.

A simple check for empty content on line 141 would fix this. Something like:

if ( empty($content) ) return $content;

If you don’t have time to update the plugin, is there any way I can contribute? Through github / bitbucket or similar?
