8BitDo 64 controller test build 2 (not a normal release)

This is 1.5.1 plus a fix for the 8BitDo 64 in DInput ("D") mode, and the
controller log from test build 1. Nothing else changed.

What to check (Windows):

1. Download Birdman64-windows-x64.zip and unzip it.
2. Set the controller's back switch to D (DInput), plug it in and start
   the game.
3. C-up, C-down, C-left and C-right should now act as the matching C buttons
   (also in the Controls menu), and pressing R should no longer leave C-up
   stuck.
4. With the switch on S (Switch), the controller's input is ignored and a
   message suggests moving the switch to D.

If something is still off, create an empty file named pad-debug.txt next
to Birdman64.exe before starting, reproduce it, and attach the file to the
issue.
