runit-scripts: frontend

add pkill to kill X when sv stop is run
apply fix based on patch from FS#533.
This stops the frontend from always shutting down after 4 kills.
get the number of these terminations that are more than 10 seconds old.
if more that 2 terminations (files) are greater than 10 seconds old
then stop the frontend from future automatic restarts and delete all the files and print error message to the log.
closes FS#522
