Added strict mode

[Algiras]

I need to generate random passwords that correlate with some guidelines.

• Always have at least one upper-case letter
• Always have at least one special symbol
• Always have at least one number

To do so I will need to add strict property and set it to true. This way it will obey the specified rules. Hope you like it! Test it out, tell me what you think.

@Algiras thanks for taking the time to put this together. There's been some discussion around this idea in https://github.com/brendanashworth/generate-password/issues/4 — are you also under the OWASP guidelines?

What else do you need to merge the PR?

Overall, this looks pretty good. This helps out with my requirements as well.

One thing I can nitpick at is the spacing. I think this project uses 2 tab indentation (4 spaces per tab). It makes reviewing the diffs a little more difficult with the spacing changes here.

I'm still trying to decide on how I feel about the "entropic" concerns brought up.

Yes, the spacing should be fixed but that isn't particularly important — I want to nail down the algorithm first. @Algiras I really want to commend you for your work and time on this, thank you very much for sticking with me. Then it'll just be nits, I can merge it, and get a release going for you.

Also, I was wrong about the entropy, sorry about that :)

Hope you like the regeneration approach: https://github.com/brendanashworth/generate-password/pull/7
