The implication is that there were formerly about a half dozen different 
mechanisms in the code for calling external utilities.  This migrates 
all of those calls into one (hopefully) cross platform class.  It also 
adds three new glorious management threads for those of you worried 
about mythbackend taking up more threads than your xterm.
