Early Roguelike Collection: xrogue/weapons.c annotate

annotate xrogue/weapons.c @ 200:1cd604c827a3

Advanced Rogue 7: initialize multiple variables. MSVC complained that they might be used uninitialized. In some cases, this might have been possible. XRogue already has initializations for all these variables.
