Add passphrases option about password.live

[devshawn]

Do you want readable passphrases with words from a dictionary?
Or passwords with spaces allowed? Or both?

[kylehakala]

• Spaces toggle for any style of password/phrase • Readable pass phrase option w/ automatically added spaces (with advanced option to change the delimiter to hyphens/underscores)

[kylehakala]

Opened separate issue #30 for adding in the option to include/exclude the spaces character

Bumping this up to see if this is something you feel can be done reasonably.
