…asn't working from cocoapods. Also this is more intuitive when u can configure those things from code and not thinking where exactly u should add those localized strings for 3rd party bundle. Added localization files for english and russian in demo app.

New method lock screen. U can call it when app goes to background and it will handle everything itself. It will check if there is pass code set, and if input is already displayed. Also lock screen doesn't have close button. Probably button for lock screen should be added in config, in case somebody whants to provide help or different action in case user is stack on lock screen. I will add it later. Also, if input is already shown while displaying lock screen it will be dismissed and replaced by lock screen. Did it to avoid situation when user entered input mode from app and screen has close button, and then u lock ur app and go back. This way u could theoretically close input and gather some info whithout entering pass.
