mcserver/source/cWebAdmin.cpp
faketruth de29399987 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
