Individual ForceField classes have been removed (they were essentially
all duplicates anyway).  

ForceField has moved to brains, and since only one force field is in
play at any time, the ForceFieldFactory and Register methods have been
removed.  

updated copyright notices

Splitting out ifstrstream into a header and an implementation.  This
means that much of the code that depends on it can be compiled only
once and the parallel I/O is concentrated into a few files.  To do
this, a number of files that relied on basic_ifstrstream to load the
mpi header had to be modified to manage their own headers.

removing cruft (atom numbers, do_pot, do_stress) from many modules and
force managers

Fixed a typo so that we use "Freq" instead of "Frq". 

Changes for implementing Amber force field:  Added Inversions and
worked on BaseAtomTypes so that they'd function with the fortran side.
