Update ASCII-ART-COMPETITION

Added arbitrary names for future reference
First review of ez_process and ez_p2p

I used pylint for code analysis. Removed nonneeded modules. Removed spaces
around keyword assignments. Removed spaces before or after ')'/'('. Added some
questions that @JNicL has to clearify. Replacing filter in favor of more
pythonic list comprehension.

Coverage is still alarmingly low (35 %, 22 % and 62 % for p2p, packet and
process, respectively). I have the feeling that there are deserts in the code
that are never touched at all. Even if you feel that you can't write proper
tests with eq_'s, at least call everything that is working such that we can
identify what can be removed or put into an attic file. It is even more
convenient than calling everything by hand with the mini-CLI.
