[Plugin: Watermark RELOADED] two quick improvements

Hello!

Nice plugin, but there are couple of small…ish issues:
1) notice warning. Always develop stuff with error_reporting(E_ALL). So, on loader file, instead of:

if ($_GET['action'] == 'error_scrape') {

You should have:
if ( isset( $_GET['action'] ) && $_GET['action'] == 'error_scrape') {

Bam, one warning fixed 🙂

2) List all image sizes. I wanted to add watermark on custom image sizes as well. So, instead of having:
foreach($this->_image_sizes as $image_size) : // line 680
I changed to:

$all_sizes = get_intermediate_image_sizes();
foreach($all_sizes as $image_size) :

Done!
