If you feel there might be another bloodline you'd like to see, what is required to make them:
name, short desc (like in <help bloodlines>), 8 spells of L1-L8 from sorc spell list (type <spells sorcerer>) that will map onto it. we don't implement other features because lazy.
if youre an imm, edit /include/bloodlines.h and bloodlines helpfile
then run <update /std/class/sorcerer>
