Add more basic attacks

[100]

There are many possible attacks that have not yet been implemented.

Some of these include:

• Phrase-level attacks
  • Invert part-of-speech order
  • Change tense
• Replacing words with homonyms, or symbols that are pronounced as a homonym (ate -> eight, for -> 4)
• Surrounding characters (or other alternating patterns) (bank -> (b)(a)(n)(k))
