Idle handling for dpms/lockscreen et al

Browse source 
Swayidle handles idle events and allows
for dpms and lockscreen handling. It also
handles systemd sleep events, and can
raise a lockscreen on sleep

Fixes #541

# You can get the names of your outputs by running: swaymsg -t get_outputs
### Idle configuration
#
# Example configuration:
#
#exec swayidle \
# timeout 300 'swaylock -c 000000' \
# timeout 600 'swaymsg "output * dpms off"' \
# resume 'swaymsg "output * dpms on"' \
# before-sleep 'swaylock -c 000000'
#
# This will lock your screen after 300 seconds of inactivity, then turn off
# your displays after another 600 seconds, and turn your screens back on when
# resumed. It will also lock your screen before your computer goes to sleep.

<description summary="User idle time manager">
This interface allows to monitor user idle time on a given seat. The interface
allows to register timers which trigger after no user activity was registered
on the seat for a given interval. It notifies when user activity resumes.
This is useful for applications wanting to perform actions when the user is not
interacting with the system, e.g. chat applications setting the user as away, power
management features to dim screen, etc..

# NAME
swayidle - Idle manager for Wayland
# SYNOPSIS
*swayidle* [options] [events...]
# OPTIONS
*-h*
Show help message and quit.
*-d*
Enable debug output.
# DESCRIPTION
swayidle listens for idle activity on your Wayland compositor and executes tasks
on various idle-related events. You can specify any number of events at the
command line.
# EVENTS
*timeout* <timeout> <timeout command> [resume <resume command>]
Execute _timeout command_ if there is no activity for <timeout> seconds.
If you specify "resume <resume command>", _resume command_ will be run when
there is activity again.
*before-sleep* <command>
If built with systemd support, executes _command_ before systemd puts the
computer to sleep.
All commands are executed in a shell.
# EXAMPLE
```
swayidle \
timeout 300 'swaylock -c 000000' \
timeout 600 'swaymsg "output * dpms off"' \
resume 'swaymsg "output * dpms on"' \
before-sleep 'swaylock -c 000000'
```
This will lock your screen after 300 seconds of inactivity, then turn off your
displays after another 600 seconds, and turn your screens back on when resumed.
It will also lock your screen before your computer goes to sleep.
