change file requires to work properly with ruby 2.0.0 nitrous.io env

remove bidirectionality of ship and part for now

don't ask :P

oops

cut out the middleman and just use attribute delegation

use instance var loop instead of setting each corresponding attribute individually, also let's try to follow Sandi Metz' rules a little more by breaking up methods

clean up a few things that didn't make sense

tidy up ancients, add a few functions for a.i. combat

add ship destroy test, modify attack function to deal damage

fix ancients and add rspec for them

new ship test spec, attack method added

overload comparison operator for ships, add initiative queue building to rspec, add some more part definitions

add a few more parts, clean up rspec for ship tests

clean up parts code, update rspec parts test

remove Node.rb, as it was renamed to LinkedList
