Broken link replacements when /xyz.html shared ssl

Hi Mike,

I found the error causing contact form 7 to fail sending with a shared ssl hoster set up in https plugins settings.

all links that start with / e.g. /testpage.html will be replaced the wrong way by the plugin:
-> ssl.proxy/testpage.html
instead of
-> ssl.proxy/domain.com/testpage.html

as contact form 7 outputs the form action also as /contact-form.html it will break when activating wordpress https for it on a shred ssl hoster.

using jquery until a fix becomes available:

jQuery(document).ready(function( $ ) {
	$('form').each(function(index ) {
		old_action=$(this).attr('action');
		new_action=old_action.replace('ssl.proxy.com/','ssl.proxy.com/domain.com/');
		$(this).attr('action', new_action);
	});
});
