Add am-refresh target
Remove useless maintainer scripts

These don't do anything except possibly run debhelper snippets.
Debhelper is perfectly capable of creating an otherwise-empty maintainer
script all by itself if needs be, so remove them.
Update packaging

This uses the "debian directory directly in upstream source" paradigm,
with the debhelper "dh" command sequencer.

To make things work properly, we add also a more recent compat level as
well as a few extra debhelper config files. In addition, remove the now
unused .dirs file.
Update packaging for php-gearman

Similar to the APC packages, now use the debhelper "dh" command sequencer.
Add the init script

This was still missing from the package, so make sure it's there again.
Update packaging for geoip

similar to other two
Update php-igbinary
Update packaging for imagick
Update packaging for mcrypt
