init: Add a command line option to start AwesomeWM without screens. This commit add an optional `--screen off` command to initialize Lua without first adding the screens. This is inconvinient for most users since it restrict the APIs that are usable out of the box. However, this allows AwesomeWM to work independently from the hardware. This means that when a screen is unplugged, it is the Lua code that will remove the screen instead of CAPI pulling the carpet from under. It also allows to ignore some screen areas before the screen is ever created. Combined, it makes it possible to work with screens even when they are physically disconnected. Finally, it will allow for an awful.rules like API to control how screens are created. All in all, some people need this for their setup and some people might want to do it anyway for fine grained and/or dynamaic multi-screen setups. This commit also adds 4 new signals to `capi` to be able to execute code at specific points during the initialization. The commit improves naughty error notifications to work even if problems occurs before the screens are added. Note that AwesomeWM will exit if no screens are created. While it would be easy to just call `refresh_screen();` after unsetting the magic variable, doing so would have corner cases. Better be harsher and prevent the user from shooting themselves in the foot from not reading the f****** manual. Code introduced in future commits will take care of automatically calling fake_screen in the event nothing is created. Fixes #1382
