Completed the replacement of setSet with topoSet

topoSet is a more flexible and extensible replacement for setSet using standard
OpenFOAM dictionary input format rather than the limited command-line input
format developed specifically for setSet.  This replacement allows for the
removal of a significant amount of code simplifying maintenance and the addition
of more topoSet sources.
