Description:

Raised by some dialog's 'Cancel All' button.

If unhandled, this is equivalent to raising the AbortOperationRequest.
However, some applications catch this signal when performing an operation
on multiple objects (such as a fileBrowser, when deleting multiple files).
In these situations, Abort is typically caught to cancel a single
operation, while AbortAll is used to cancel the whole action.

Class protocol:

 initialize

self initialize

 handleAndAnswerQueryIn: aBlock

evaluate aBlock, and return immediately, if the AbortAllRequest is raised.
Answer any query if AllOperationWanted with true.

usage example(s):

AbortAllOperationRequest handleAndAnswerQueryIn:[ AbortAllOperationWantedQuery query ifTrue:[ self halt. AbortAllOperationRequest raise. ]. ].
