Update and rename alpha.html to archery.html

yay; code cannibalism. ok, so i'm starting with the code from the last project and working by way up from there. changed the color of some things, decided to keep the img elements but will of course swap them out for more appropriate pictures. everything's really in alpha right now but that's what happens when you start later than you'd like to (other assignments and stuff). oh, also i found a way to make the video thing work; really happy about that.
