two bugs: please fix

Hi Ralf,

I found two bugs:

First:
If you have whitespaces between <a> and </a> CryptX doesn’t work.
The Regex at line 226 in functions.php should be /<a (.*?)(href=("|\')mailto:(.*?)("|\')(.*?)|)>\s*(.*?)\s*<\/a>/i

Second:
If you have declared a target in an anchor CryptX doesn’t work correctly.
So you have to add at line 238 in functions.php:
$return = preg_replace('/target=((\"(.*?)\")|(\'(.*?)\'))/i', '', $return);

Regards
Patrick
