This commit removes a couple of files connected to setting up the disk,
which broke 1.3.1 and replaces them with a single file
(previously configure_device.sh) from 1.3.0 (when it wasn't broken).

Added file permissions to profiledef.sh and made the main anarchy script
non-executable, since profiledef will make it executable.

Closes #92

Move set_keyboard_layout() into a new script and run it before start_menu()
to allow user to set keyboard layout before entering wifi password.
