Added four more side effects.

These rely on some compiler transformations of variable names
into strings (as well as the existing __global dictionary.)

Only the OF-specific rules remain.
Added OFSideEffect class/object.

Should be used by the OF Module as well as the DSM to exchange
information about OF rules to use.
Fixed up some variable/argument names.

The argument names to the functions are not string literals, they
are variables that will take on whatever value is given them by the
calling code.
naive sender and sniff function

Test on sniffing a fixed port, and it worked. (install instruction and
snifflog are not important--just find some place to take note, write
someting.)
one-way controller

one-way controller, but which thing to forward?
dsml_controller, bug exist

nw_dst, nw_src match simply be ignored
fixed a heartbreaking bug...
