.. they were removed from code recently but still
lingered harmlessly in the codebase.
.. now moving into the deprecated folder to stop

Added Specification parameter to AddIntervalDialog::findPeaks
So it can be used as a more general replacement for
BestIntervalDialog::findBests and findBestsKPH
.. we can register routines when embedding via the
R_getEmbeddingDLLInfo()
.. so we just register our functions directly now
in RTool rather than needing a dynamic library.
.. its cleaner and there are no nasty casts and build
settings required
