The library is no longer automatically used during disambiguation.
It is used only when the user press the More button or when he selects
the library from the Debug (?????) menu!
Moreover, using the library or not using it has now a different behaviour:
1. when the library is NOT used, symbols with no preferences are no
longer automatically looked for in the library
2. when the library IS used, only passes 5 and 6 are tried.
CONS:
1. the Debug menu voice is now necessary: move it elsewhere? always open the
disambiguation window making it non-modal? put an hyperlink in the error
message window?
2. when the library is used, all previous preferences are completely ignored
for all symbols. This makes the system much more stupid than what it used
to be.

disambiguation is now much faster in case of error
