Add OP_GET_MORE and OP_DELETE

Created legos for these two db messages
Add all high level messages to ..../legos/mongo.py

All legos are added but untested. They have been added to the bin
in the __init__.py file so that they are callable with the s_lego
function. Imports from the primitives file were changed to remove
clutter from the code. A simple request was made for a get more
message.
Added __init__ line to two classes
Missing # in comments
Removed mSulley folder, created main for network monitor

Sulley directories are now in its original form. The __main__ of
the network monitor has been placed into a function called main
so it is callable from another module. This way the network monitor
does not have to be copied to another directory.
Change network_monitor's main to run_monitor
