Roadmap:
Update caffeine to:
- run correctly first time (https://bugs.launchpad.net/caffeine/+bug/691759 ??)
- change flash so caffeine reacts to any shell command, add full screen flash as a default option
- add default and extra Actions to every trigger so, for example, full screen flash only stops locking for a few hours - may be good if you want to fall asleep to streaming video!
