Dynamically enable stylus and eraser remapping.

A bit of a cruftectomy; removed most of the reportage displays,
and enabled dynamic scanning of the device list so that the
stylus & eraser now remap automatically, even after they've
been added dynamically via modprobe.  Signficantly reduced
the number of shell-outs as well

As is my usual nature, I removed almost all the case handling and
replaced it with a table, which is DRY: Every piece of knowledge must
have a single, unambiguous, authoritative representation within a system.
The table has a name, number, transformation matrix, and x and y
orientation check functions.  Everything else is just checking on
that.
