Pin code removal of 4 digits limitation

@klh
Don't understand why you tell me that

@keneda Oh, I misunderstood your post as recommending the 12 character, text field and manual submit as the requirements for the screen lock, sorry

@lduboeuf Thanks for your work, after thinking twice, at startup would be to put an empty circle blinking, as you fill with the key the empty circle and blinking moves forward, when you finish with the key the filled circles stop and opens directly the screen lock.

Regards...

@josele13 yes that's an idea ;-).
I think i will just start with the less possible change. Meaning just allowing more than 4 digits and no change regarding UX ( empty dots that have the length of expected pin code and auto-login ).
Improvement can come afterward.

I love this idea. Im very used to 6 diget codes nowadays so id love this to come to ubuntu touch.
