Add comparison operators for stats

[greenstack]

Allowing stats to be directly comparable to a value of its internal type would be a huge QoL improvement. These should work on current values.

Do you need "==" and "!=" in the IStat's operators or just ">, <, >=, <=" its enough?

I think having == and != would be helpful in the long run.

I think you forgot to close this issue.

Yup - life's been hectic for a while now and will be for the next bit. Thanks for letting me know!
