Subject: Converted entire Core plugin including WebAdmin interface to new
 plugin method/system/thingy and sexyfied it. Made some changes to WebAdmin to
 make the new plugins work Old plugins still work like they're supposed to Not
 all hooks have been programmed for the new plugins yet, this still needs to
 be done
