[2.2] fixed the value format in stock field with wc_stock_amount(), closes #6622
Update WooThemes.com extension category archive links.
Fixed constant value cropping to option setting

I don’t think that it is the right way to set the cropping by checking
if the ‚crop’ option is set because it could have been set to 0 in the
options. In that case it would be cropped either way because isset
would also return true.

Avoid notices if file does not exist

1. I've got notices on files
my-theme/woocommerce/single-product\add-to-cart\bundle.php,
my-theme/woocommerce/single-product\bundled-item-image.php,
my-theme/woocommerce/single-product\bundled-item-title.php
which are Template Overrides (WooCommerce Product Bundles)
and do not exist in the WC plugin.

2. There should be a more elegant way, because this is just to shut up notices. No version comparison performed.
