Language overrides in language manager backend

[Margriet]

Just discovered that strings or constants of VM languagefiles don't appear when searching in language manager.
Would be great if you could add this.

Works fine for me with VM 2.0.1h

It works, but not in obivious way, as far as I see.

I.e. I have Russian language.
There are 2 constants in the current VM dev version:
COM_VIRTUEMART_CART_SHOW
COM_VIRTUEMART_CART_SHOW_MODAL

But Russian translation doesn't include
COM_VIRTUEMART_CART_SHOW_MODAL , which I want to overrride now to show it in correct way.

But joomla language manager finds COM_VIRTUEMART_CART_SHOW and not COM_VIRTUEMART_CART_SHOW_MODAL.
