Extension policies: Only one category

[htcfreek]

Combine the categories "Add-ons" and "Extensions". This can be done without any impact if you only change the category name.

Oh interesting. It will automerge so I don't have to change OMA URIs?

I checked this and if I change the category name, we end up with two categories.

There's no easy way to combine them without breaking legacy policies. I will move these in the next ESR.
