Basically pmemd.cuda only supports 12-6-4 interactions when ntb > 0. Before
update.10, the program would fail to exit properly when 12-6-4 interactions
were present and ntb=0.

Notes:

1. I'm not sure this is the cause of your error: if you indeed have ntb>0,
then we'll need more details about what other options you have selected in
your input code.

2. cc-ing do Dave Cerutti: Dave: the error message above is not specific
enough. All the other messages in update.10 indicate exactly what what the
incompatibilty is, but this one recycles the old, non-specific error message.
Can you fix this (just in git master, I think)?
