Add support for RandR 1.5 monitor

Browse source 
* exwm-randr.el (exwm-randr-workspace-monitor-plist): New user option
for specifying which monitor each workspace should be displayed on.
(exwm-randr-workspace-monitor-plist): Made obsolete.
(exwm-randr--get-monitors): New function for fetching active monitors.
(exwm-randr--refresh): Adapted to use monitor.
(exwm-randr--init): Now requires RandR 1.5.

* exwm-randr.el:
* exwm-workspace.el: Rename `output' to `monitor'.
