Add a dynamic "Done" or "Enter" instead of a forced hard coding password_length

[NathanaelA]

We can add a "Done" or "Enter" options in addition to the 0-9; to signify that the password is complete. This will allow us to support any different size password length dynamically at the same time. If password_length = 0 OR any passwords in the database don't match the set password_length, then we switch to dynamic mode and add a "Enter" or "Done" to the Virtual Folder.
