// Ok, Greg, the action pointers thing was bad enough, but this really
// takes the biscuit.  Why does HHE's text replacement address strings
// by offset??!!  The dehacked way was much nicer, why change it?
//
// Anyway, this is the Heretic 1.0 string table, which can be seen in
// HHE.  This is the string and its offset from the start of the
// text section.  Not all the strings are here; this is a redacted list
// that contains just the strings we support.
