SAILOR probably shouldn't have "footpad" as one of its synonyms (breaks Zork II)

[eriktorbjorn]

This object is defined in globals.zil:

<OBJECT SAILOR
	(IN GLOBAL-OBJECTS)
	(SYNONYM SAILOR FOOTPAD AVIATOR)
	(DESC "sailor")
	(FLAGS NDESCBIT)
	(ACTION SAILOR-FCN)>

Unfortunately, it clashes with Zork II's FOOTPAD obejct:

<OBJECT FOOTPAD
	(IN GLOBAL-OBJECTS)
	(SYNONYM FOOTPAD)
	(DESC "footpad")
	(ACTION FOOTPAD-F)>

<ROUTINE FOOTPAD-F ()
	 <COND (<VERB? EXAMINE>
		<TELL "A footpad is a thief." CR>)>>

In the released version, you can ask the game what a footpad is:

>WHAT IS A FOOTPAD
A footpad is a thief.

But in Zork II compiled against zork-substrate, you instead get:

>WHAT IS A FOOTPAD
Which footpa do you mean, the footpad or the sailor?
