Add support for aliases

[zhouzi]

The search algorithm should also be able to match aliases. For example, Villentretenmerth is sometimes abbreviated "Vil", Yennefer called "Yen".

Actually, the search algorithm will probably match abbreviations so I'm wondering if there are really cases where we'll want to add aliases. If not, this issue can be ignored and closed.

Starting with #22 we will able to add multiple entries in the dictionary for the same card (that's what is done for plurals).

Look up https://github.com/PabloSzx/Gwent-Cards/blob/master/src/data/nicknames.json maybe you could ask Pablo if you could use his alias file.

Thank you very much @Tri125, that is indeed an interesting list!
