empty link added to non-products

After installing the 5.x-2.09 version of this module, an empty link started to appear on all my pages (not just product pages):

<div class="links">&raquo; <ul class="links inline"><li class="first last add_to_cart"></li>
</ul></div>

Turns out this was caused by a faulty E_ALL check in ec_live_subproducts_link(). The 5.x-2.x-dev code “fixes” the issue by removing the E_ALL check, but that check really should be there.

The attached patch corrects the E_ALL check in 5.x-2.x-dev.

On a related note, why does the ec_live_subproducts_link() function even exist? All it does is add an empty link to product pages.
