Feature request: Adding entry to remove old kernel versions

Hi Adam,

I just came across a very useful resources on eOS Stackexchange:

http://elementaryos.stackexchange.com/questions/95/how-to-remove-old-kernel-versions

The following one-liner allows you to remove all old kernel versions:

sudo apt-get purge $( dpkg --list | grep -P -o "linux-(headers|image)-\d\S+" | grep -v $(uname -r | grep -P -o ".+\d") )

What do you think of adding this one-liner as an entry to the Action menu in Power Installer?

Thankfully,

Robert
