Option to change iris size

Is your feature request related to a problem? Please describe.
It seems there is no option to change the iris size in the character tab. I think it is the only option from the character creator that is missing. I couldn't find it in CMTool either, so maybe there is a reason for it.

Describe the solution you'd like
Add an option to change the iris size in the character tab.

You can change iros size by changing the eye number, 0-4 are small, and 128-132 are large, I think.
We should add a check box to do this automatically, though.
