Made changes so that the ptop will run without seg faulting if the

database isn't running or if the database stops while ptop is running.
The system summary info will still update but there will not be any
processes displayed.  Tried to get a message to display that the no
database connection was made.  That can hopefully be fixed in a later
version.
