Add the ability to mass purchase a deck on TCGPlayer

[AlanOC91]

The TCGPlayer Mass Entry tool allows you to pass a string query into it so bulk purchase a deck.

Example format:

https://store.tcgplayer.com/massentry?partner=YGOPRODeck&c=||1 Dark Magician||3 Time Wizard||2 Thousand Dragon||

Parameters:

?partner= - This is the partner ID code for the affiliate website.
&c= - These are the cards to be added into the tool.

The cards themselves must be between || and require a number before the card name. I believe the number cannot come anywhere except before the card name.

There may also be a parameter to set the default "Product Line" to "YuGiOh" but I haven't been able to accomplish this yet.

&productline=Yugioh will set the default Product Line to "YuGiOh"
