Stubbing in the other readMdata files.  Improving the makefile a bit.
added traps
stubbed out test functionality for all of the MDATA files
fixed typo in error message
added file sizes for each mdata file, assuming that the onse I've got are gospel
fleshed out the basic component of readMDatat2.cpp -- reading in a spell
Looks like we can read the spell data now.  There are large segments of dead information in the file if that's actually true.
