Update bad.json and generator.js

[dangowans]

Two updates. My apologies for them being grouped together. GitHub did it, : )

The first, bad.json. Feel free to discard this PR if it goes against your plan for the project. The goal of this PR is to try to group together alternate spellings and remove redundancies.

For example, if generated passwords with the word porn are discarded, then there is no need to further search for porno and pornography. There is also no need to search for plural versions of bad words when the singular versions are already in the list.

The second, generator.js. I see that when bad words are found, a new password is generated, but it is being generated on top of the last generated password without restarting the search for bad words. That makes it possible to have a regenerated password use a bad word from earlier in the bad words list.

In regards to the generator.js update, I misspoke. It's not that bad words will be missed if the password needs to be regenerated. Rather, the bad words list will be scanned on the final password multiple times.
