isn't it better to put this before blink resources (probably next to ash)?

I do not want to get too close to the max id used by ash_resources.grd
There is not a lot of room between ash_resouces.grd and athena_resourecs.grd I
did not feel like changing the IDs for all of the .grd files

You can just update the ids after ash

   # These files don't need to reserve resource ids, but are listed here so that
   # translation scripts know of their existence.
