pitch13 gets a face lifting -> pitch18

another lift for the hardworking pitch controller.
-a few hardware bugs corrected.
-a few parts updated.
-better input port protection.
-a few changes in the layout for better production.

pitch18 prototype arrived and will replace soon the pitch13 pcb.

the functionality is 100% the same.
-pinout of connectors is the same
-software is the same and works on all version (pitch98,pitch13,pitch18)

there is no reason to pugrade your pitch98 or pitch13. its the same.
we just keep the hardware as actual as possible.and we need less time to produce
and the result is more reliable. thats all.
