Refactoring and whatnot

[agvxov]

I used pseudo hash for a personal project, however I needed more fine grained control over the generated password list than what was possible over the cli.
Long story short, while initially wanting to make small edits, I ended up changing every line.

Here is the list of changes:

• removed orphaned function unique()
• normalized camelCase
• moved argument parsing into a function;
  for the same reason main() is a function;
  either the ability load as a module or readability,
  choose whichever explanation you like
• aligned code
• fixed oversights such as if b: return True else return False and for a in A: B.append(a)
• def ask_for_consent()
• def illegal_years_input() # (the original repeats itself); this is a very questionable restraint btw
• trans_keys should have never existed; transformations is a dictionary now, instead of a list of dictionaries
• simplified year range split
• moved runtime configurable data into object opts, instead of having them half split between globals AND args;
  opts is declared at the top with its defaults, making the script much nicer to peak into during "work"
• print error if the output file cannot be created, instead of just throwing
• pass the wordlist file as an argument to mutating functions;
  i haven't benchmarked it, however, i'm positive repeatedly opening and closing a file takes time
• "seperator" is not a word, "separator" is
• --no-transformations flag
• a config script is attempted to be imported; this allows users to modify all globals very cleanly (e.g. passing transformations from the cli would be awkward; words could be dynamically generated)

I know having only one commit makes code-review significantly harder. I'm sincerely sorry about that.
