/* TODO

# improve the list of websites to include
## consider include * then refine pattern per task
# make timers (default to 0 sec, value defined via the script or a GM_Value) to be more flexible
## reset timer either manually or per day (i.e.) reset if last set date <5AM
## set 2 thresholds, the first as a warning, the second as an action

Note that it does work even when Flash has focus.
