I'm not exactly sure what's best here, but I know it doesn't belong in
the *gate*.  My idea is to have a table object that shows up in the
schematic, like in a corner or something, that lists all the power
pins and what nets they connect to.  I've seen other schematics with
this, it seemed much cleaner than what we do.

How we populate the table, who is responsible for it, how the user
edits it - if it's even in the schematic at all - is TBD.  Heck, you
don't even know what the power pins *are* until you've selected a
package, and that's way down the line flow-wise.

As an aside, support for a table of pin mappings opens itself up to
FPGA mappings, too - just supply a CSV instead of trying to map it to
a schematic.
