Folder structure capitalization typo prevents compiling sketches.

[johnnaglak]

Hi! I had some trouble getting sketches to compile. I was getting an /arduino/Arduino.h:258:10: fatal error: pins_arduino.h: No such file or directory #include "pins_arduino.h" error when using the Board Manager and when manually installing the board definition.

After some trial and error, I identified that the path /Firmware/ast/avr/varients/can485 does not match the capitalization of Can485 in

CAN485/Firmware/ast/avr/boards.txt

Line 10 in ff5446b

Can485.name=Can485

My solution was to manually edit and capitalize the folder name /ast/avr/varients/Can485 on my system. This should be a fairly simple fix in the repo.

Thanks, looking forward to using the board!
