Save auxiliary wrestler information for each bout

[Zomtir]

There are currently two auxiliary attributes that have to be checked by the referee before a match:

• Youth status: Is the wrestler over the age of 18
• Foreign status: Has the wrestler be a resident in the country for a certain amount of time

Although the youth status can be derived from the date of birth and the foreign status is bound to the residency, both should be recorded for each match similar to the weight.

Reasoning

• Youth status: Sometimes the date of birth is changed/corrected due to uncertainties or misrepresentations. Very rare occurrence, but not unheard of.
• Foreign status: Obtaining a new citizenship or a moving to a new residency are two common reasons for a change in the foreign status.

In both cases, solely relying on the persistence of the data for a wrestler will result in a loss of information for a specific match. The age and current residency should be used as plausibility check for new match inputs, but never retroactively change the information of old matches. For new line-ups the last match can be used as reference for the attributes.
