Skill tree unlocking

[Tainted-Valor]

I would very much appreciate the ability to make skills only appear in the skill tree when you meet the requirements. an additional request of lesser priority is for the ability to set more requirements for skills to be unlocked and in more detail.

1. Add option to hide skill if requirements not met in the details page
2. Add the ability to list more than 1 required skill in the details page
