Arguments are now handled with argparse

- User can pass verbosity option
- User can specify a config file, overwriting default bom.ini
- User can not specify an output file, and a default output will be used
Preferences object now has a verbosity switch
This will be (eventually) passed down-stream to relevent places
Added zener aliases
Added diode aliases
