Changes on BASE, from 1.6 to 1.7

enhancements:
	sprintf-like parameter insertion for strings

modifications:
	get rid of an unnecessary polymorphism selector
	(Character>asString, the only send was in Application>sourceIdentifierForVersion:);
	lots of programmers went into a trap when using that code 
	without Application Management loaded

removed selectors:
	Character>asString
	Filename class>stringFromArray:

NOTE:
	You should carefully check for further sends to Character>asString .
	Either replace the calls or backup the method and reinstall after upgrade
	of BASE.
