Rename squad members in Squad Management window (animals mainly)

[Zeal]

This is mostly for the case of animals, but I could see it also applying to normal units. This is relation to This thread on steam where someone asks to be able to rename animals at plastic surgeons. Since animals have no interaction abilities, being able to rename squad members in the squad management as suggested by Shidan would be a simple solution to this.

This was mentioned before. Basically you shouldn't need a plastic surgeon to change someone's name. Should be able to just start calling them "Gutter Meat" with minimal effort.
