Request: Kill the chrome process on crconsole's exit

[jsdevtom]

Upon exiting the crconsole, the chrome process is left running. For example:

$ crconsole -s
Waiting for chrome to start: 
chrome://newtab/
> SW registered
newtab> .exit
^C

Does not close the browser.

@1db8k it's a bit hard to figure out which process to kill - chrome forks after initial start and there are multiple processes to track
