Duplicate of another recent report as far as drain resistance from
Excalibur/Stormbringer/Staff of Aesculapius not being shown by
enlightenment goes, but this one mentioned that it also wasn't being
shown for lycanthropy. Being inflicted by that does confers level-
drain resistance. were_change() wasn't calling set_uasmon() since
it isn't changing youmonst.data, but set_uasmon() is were intrinsics
conferred by creature form are set up. So call it when changing
were-form. Direct access to u.ulycn wasn't calling it either, so add
a new routine to assign the value to that instead doing so directly.
