// Only called at game initialization in order to list the set of switches
// and buttons known to the engine. This enables their texture to change
// when activated, and in the case of buttons, change back after a timeout.
//
// This routine modified to read its data from a predefined lump or
// PWAD lump called SWITCHES rather than a static table in this module to
// allow wad designers to insert or modify switches.
//
// Lump format is an array of byte packed switchlist_t structures, terminated
// by a structure with episode == -0. The lump can be generated from a
// text source file using SWANTBLS.EXE, distributed with the BOOM utils.
// The standard list of switches and animations is contained in the example
// source text file DEFSWANI.DAT also in the BOOM util distribution.
//
// Rewritten by Lee Killough to remove limit 2/8/98
