Detect and apply patches on pm-update

[Former user]

I was testing and noticed that 'drush up' does not trigger this excellent module like 'drush dl' does. I sort of expected 'drush up' to trigger download hooks this plugin would see; but, alas, it does not seem to be that way.

It would be awesome if patches applied on pm-update updates.

This patch is exactly what we need, to automatically patch modules after each update.

Having this feature would greatly simplify our update process.
