Allow to set integer values for EnumDiscriminants

[Shatur]

EnumDiscriminants generates an enum without data, but it would be nice to be able to provide additional integer meta-information in C-style. There is EnumProperty, but it supports only strings.

This should be doable. I'm inclined to say EnumDiscriminants should copy over the discriminant value from the enum as well if they exist. Is this something you're interested in working on?
