Brenw0rth Pync Versions Save

• Remove Netcat.start() method.
• Added Netcat.start_process/start_thread methods.
• Added Netcat.run() method that calls readwrite and closes after.

Netcat classes no longer directly store sys.stdin/out/err file handles. This is to prevent multiprocessing.Process throwing an error when trying to pickle. multiprocess.Process and threading.Thread can be useful for making proxies etc.

Refactor NetcatFileReader/Writer classes.

• pync.Popen class for plugging processes into Netcat classes (use this instead of subprocess.Popen).
• Netcat stdin and stdout pipes for plugging into other Netcat instances (to create proxies etc...).

• Added -y option to execute a string of python code.
• Added -Y option to execute a python file.
• rename StopReadWrite -> NetcatStopReadWrite
• Refactor of readwrite method.

Allow arguments to be passed to program when executing with the -e option.

-c and -e options for command execution.

Changed -e to --exec. More current versions of the openbsd netcat have an -e option. Changing pync's -e to --exec is to avoid conflict in future versions of pync where I want to implement netcat's -e option.

• fix issue with parsing -w flag (forgot to return value from argument type).
• Added timeout for client udptest.

Added the -w flag for connection timeouts and final net reads.
