Add VSG Mintaka keyboard

[pudymody]

Hi, i was trying to reverse engineer this for myself, but reading this issue and pull request i found out that my keyboard is a sonix one.

Here is the code for everyone else interested. Its just a recode of the pid/vid and led values as this is a 60% keyboard. It also adds a few key definitions because its an iso spanish one.

Thanks for this amazing software, it saved me a TON of time. Keep the good work.
