cmd/godoc: move note argument to godoc.go

Fixes the App Engine version of godoc. The other fix is to duplicate
this code inside appinit.go. I think initHandlers is the right place
to put the strings.Split call, as the notesToShow var is used by
docServer, which is what initHandlers sets up.

image/png: always set up palette during DecodeConfig

The old code would decode the palette only for 8-bit
images during a DecodeConfig.
This CL keeps the behavior for 8-bit images and sets
up the decoded palette also for 1, 2 and 4-bit images.

Fixes issue 4279.
