Rename resume: source -> retryWithNewSource: source.

The purpose of such exception handling is indeed to retry the compilation with new source.

The purpose of resume: anObject is to return anObject to the context that sent signal, that's a slightly different semantic.

It happens that if we resume after setting newSource, the signaller (Parser>>notify:at:) will effectively then tryNewSourceIfAvailable.
So effectively, resuming will end up in retrying (if there is a handler of ReparseAfterSourceEditing up the sender stack, but the Parser normally puts one).

But, even if this is HOW we implement the #retryWithNewSource:,
this is not WHAT we wish to ask to the SyntaxErrorNotification.
in other words, we shouldn't let the implementation leak in the semantics, otherwise we put the burden of understanding the implementation on the shoulders of programmers, when they could just have trusted the semantics of pseudo natural language offered by keywords.

While at it, remove the accessors of newSource.
They are not used and may be considered private.
This will reduce the unecessary polymorphism.
