create a validator for names to test against a bad words list

[corp-0]

Idea being making sure people don't take certain valid names that might be offensive or misleading.

The validator should apply at the moment of creation of the Account object, similar to how we currently validate characters and should prevent people from creating their account if their chosen names are in a list of bad words.

In order to avoid commiting offensive words in plain text to github, the text file should be encoded and decoded by central command. Provide tooling for doing the encoding automatically.
