Cleanup: removed bunch of obsolete files.

Issue #108: Added some tests for issue #108 See https://swing.fit.cvut.cz/projects/stx-jv/ticket/108

Issue #108: Fixed update of method list in case methid is re-wrapped When updating method list, must (also) search for a class whose `#originalMethod` is the same as current method's `#originalMethod`. This is to handle the case a method was wrapped before and now it's wrapped again. For example the method was *Trace*d and user selects *Trace Sender*.

Issue #108: Fixed bug causing method selection loss in some cases ...when method breakpoint was installed / removed. When this happens and the method is selected in a browser, the selection collection is first update in-place and then dependents are updated. The problem was. however, that if the selection was not an `OrderedCollection`, the selection was not updated in place due to: selection := selection asOrderedCollection. Subsequent notification of dependents causes selection refetch from the selection collection which still contained original method, not the wrapped method now installed in a class so selection was removed. This commit fixes this problem. See https://swing.fit.cvut.cz/projects/stx-jv/ticket/108

On the way, more symbolic actions have added and all (even those nt bound by default) are listed in `DebugView class >> initializeDefaultKeyboardMap` for documentation purposes.
