Krav Maga weaponry (Is a tanto a Krav weapon?)

[6maboc]

Is your feature request related to a problem? Please describe.

As it currently stands, the tanto is not a valid Krav Maga weapon in default. Magiclysm also currently considers the Tanto+1 and Tanto+2 to be valid weapons.

Describe the solution you'd like

This can probably be remedied with a simple .json edit. However, I suspect that the valid weapons list may need additional changes (or not).

Describe alternatives you've considered

A more elegant solution (to me) would be to be enable white/blacklisting weapon groups through their flags, but I'm not sure if this is worth the effort to implement.

Additional context

Krav Maga, as it is currently implemented, seems to accept: batons/tonfas, knives, handguns, and rifles.
This could easily be a PR, but I wanted to ask around if there were any other potential irregularities in the weapons lists for other martial arts or Krav Maga itself.
