mailmerge: Implement toolbar controller to exclude entries.

This can be used as a "How to implement a custom widget / control in
the toolbar" example:

* the Controller.xcu change introduces a .uno:MailMergeExcludeEntry command so
that it can be added in the toolbar .xml description (in this case
mailmerge.xml)

* the swriter.sdi introduces the .uno:MailMergeExcludeEntry command for the
sfx2 handling - so that it can get notifications about enable/disable
changes, invalidates, etc.

* wrtapp.sdi + associated apphdl.cxx change make it possible to forward
command invalidates (the rBindings.Invalidate(FN_MAILMERGE_EXCLUDE_ENTRY);)
to the MMExcludeEntryController::statusChanged() for further handling
(in this case setting the checked state according to the current data)

* MMExcludeEntryController::createItemWindow() implements the custom widget
itself (in this case a checkbox, but can be any VCL widget, even a custom
one)

* the rest (sw.component and the associated getImplementationName(),
supportsService(), etc.) takes care of the instantiation of the controller.
