Make :loadsubs reload instanced personals too Right now if your subs get lost because something falls over, you have to manually sub to instanced personals to get them back. :loadsubs doesn't work. (Supposedly that code is for "backwards compatibility", but... it dates back to kretch. Probably because it's odd that :loadsubs [file] will also automatically load the default subs. But given that everyone runs :loadsubs with no argument to mean "oops zephyr fell over reload my subs please", I'm okay with adding more code to the "backwards compatibility" path. I doubt anyone actually runs :loadsubs with an argument anyway.) Also, while I'm here, get rid of that 'foo' variable. (Really? Really?! foo?!?)
