feature: make desklock hookable, break out current desklock into module, move pam stuff to separate file

after this commit, the new module "lokker" (or other loaded module) is in charge of creating all graphics for the lock screen, and it will be added to the user's config. failure to load a lockscreen module will just result in a black screen

desklock subsystem now handles all the pre/post lock stuff while the modules themselves are responsible for creating visuals and calling auth functions to determine whether to unlock the screen
