pw_cmd: Convert 'pw' into Python module; tweaks
This reworks the 'pw' single-file script into a proper Python module
with a setup.py and appropriate main() handling. It also splits the
'watch' command into a separate file.
This is the first step in adding more 'pw' subcommands.
Other minor tweaks:
- Drop coloredlogs dependency in favor of simpler solution
- Make level log component 3 characters only
- Change colors to better separate command output from logs
- Make a new "logdemo" command to illustrate all log levels
- Make a new "help" command to show top-level help
- Put some space around command output for visual separation
New 'pw help' output
