Add the option to choose a specific game to the Automated Offer

[kaioloureiro]

Example: I want a game X or Y and wanna send an Automated Offer to all users that has it on their tradables. Currently you can do it only sending an offer to Multiple Users, which isn't too much useful because the users won't receive any notification from that offer.

To avoid any issue with too many options, you can include all that "...in exchange for..." part on a radio button with two options.

The first one with all the already existing content can be changed to "...in exchange for... any game with the following options". The second one can be called "...in exchange for... a specific game".
