Update the system dashboard behavior a bit:

1) Add a signal collector/combiner for screen brightness changes (1/10 second delay) - since hardware brightness changes cannot usually be spammed too quickly.
2) Update the battery icon notifications on the panel button. If less than 5% left, leave the low battery icon there all the time, if less than 15% cause the low battery icon to flash intermittently, if greater than that don't show any battery icon.
