Udev rule syntax change

Another quick Linux aside/breadcrumb, I had some hand-written Udev rules start causing errors on my Arch boxes a while back, and just got around to fixing them.
The basic problem is that the Udev rule syntax has changed, and statements that used to be of the form SYSFS{idVendor}== will now be ATTRS{idVendor}==. The one that caught almost all my machines is the rule for giving users permissions to USBTinyISP programmers, since the documentation suggests the old syntax.
Figured out with the suggestion from Julie Pichon’s(?) blog.
