Vore Tech Icons

it might be a good idea to change the icons used for the Vore Tech's type selections to something similar to the vore flags used for Tenants. having 'O' for oral, 'U' for unbirth, 'E' for egg, 'H' for healing, and 'D' for digest. the reason I'm suggesting this is that it's hard to see what mode you're in if the zoom is too far out.
