MAX_LAYER_COUNT *is* 16.  You can bump the number of design layers
from 8 to 16 just using menu options, you only need to recompile when
you need more than 16 layers.

What I was going to do was change the default number of *design*
layers from 8 to 9.

You'd have to apply it to gsch2pcb first ;-)

In PCB, globalconst.h has MAX_LAYER as 16 and DEF_LAYER as 8.  Just
change DEF_LAYER to 9, and make sure src/main.c has appropriate
defaults for the ninth layer.

src/main.c is the place to default an "outline" layer, too.

gsch2pcb probably needs a patch to default an "outline" layer.
