SCUMM: Indy4 - Put coat/window in office, fixes bug #12420 
WORKAROUND bug #12420 (also occurs in original) Broken window and coat missing

This happens when you skip the cutscenes in the beginning, in particular
the one where Indy enters the office for the first time. If object 23 (National
Archeology) is in possession of Indy (owner == 1) then it's safe the force the
coat (object 24) and broken window (object 25) into the room to compensate for
the skipped code.

// WORKAROUND: The clock tower is controlled by two variables: 163 and
// 247 in the floppy VGA version, 164 and 248 in the CD version. I
// don't know about the EGA version, but this fix only concerns the
// CD version.
//
// Whenever you enter the room, the first variable is cleared. It is
// then set if you examine the clock tower. The second variable
// determines which description you see, e.g. "Ten o'clock.", "Hmm.
// Still ten o'clock.", etc.
//
// If the first variable was set, the second is incremented when you
// leave the room. That means that every time you examine the clock
// tower, you get a new description (there are three of them, with a
// random variation on the last one) but only if you've been away from
// the room in between.
//
// But in the CD version, someone has attempted to "fix" this behavior
// by always incrementing the second variable when the clock tower is
// examined. So you don't have to leave the room in between, and if
// you examine the clock tower once and then leave, the second variable
// is incremented twice so you'll never see the second description.
//
// We restore the old behavior by adding 0, not 1, to the second
// variable when examining the clock tower.
