	These changes allow Insight to handle the case where there are
	symbols for the source files, but the source files are not in the
	location pointed to by the symbol.

	* srctextwin.itb (SrcTextWin::setTabs): Make the "asm" type for
	the source display "S" not "", which is not very clear.
        (SrcTextWin::configWin): ditto.
	(SrcTextWin::FillAssembly): Handle all return values from
	LoadFromCache.
	* (SrcTextWin::LoadFile): Handle "couldn't find file" return from
	LoadFromCache.
	* (SrcTextWin::LoadFromCache): If the source file could not be
	found, return -1 rather than choking.
	Also change "asm" type for source from "" to "S".
	* srctextwin.ith: Change the defaults for the "asm" type from ""
	to "S" for Source display.  This is just cosmetic, but clearer.
