Attributes ignore minimum due to skill rating

[elyukai]

The Skill Rating maximum is the highest check attribute + 2. So if those levels are reached, it must be ensured the highest attribute cannot be lowered – but thats not the case currently.

There are several options I can think of that would solve the problem – but I'm not sure what would be the most efficient and practical way, especially for advanced heroes.

1. Create a selector for the attributes tab that iterates through every available skill and returns the minimum value for each attribute.
2. Create a dependency for every skill and update on each skill rating change.
3. Create a selector for the attributes tab for each attribute and iterate through every available skill to find any skills that affect the respective attribute.
