SCI: Add some comments a possible TODO regarding song looping
SCI: Rewrite the song loop comments in commit 6fa668e to make more sense
BUILD: Disable data path in mingw builds, since it was using a hard coded path. All external data files are stored in the Windows executable file anyway.
SCUMM: Add another French Windows version of Pajama Sam 2.
NEVERHOOD: Fix incorrect sound heard when pressing the ladder button

When the ladder is down, pressing the ladder button shouldn't do
anything
TSAGE: Implemented missing visual speaker methods for R2R
Merge branch 'master' of https://github.com/scummvm/scummvm
DC: Only enable serial debug output when --enable-debug is passed.

After this change, release builds will still have serial debug disabled,
but debug builds will now not provide this unless --enable-debug is
passed explicitly. This could have been another option or environment
variable, but other embedded ports do similar things with _debug_build
and this looks like the cleanest way to deal with this.
DC: Amend tests on serial disable/enable blocks.

These now restore the original release build logic to ensure that we
don't have issues with releases. Missing something here as _debug_build
doesn't seem to work as I expected...

TUCKER: Fix palette fades

This is a regression from 362b0cd5e4a71a0b2610ff8abb6aeecddc842cf0
and fixes bug #3614686.
GRAPHICS: Be more robust with broken/unsupported thumbnail headers.

This fixes future issues like bug #3614654:
"ALL: ScummVM 1.5.0 can't read newer saved games".

There are a few behavior changes introduced with this commit:

- checkThumbnailHeader will now also report the presence of
  unsupported/broken (but skippable) headers.

- skipThumbnail will also try to skip the data for broken/unsupported
  thumbnail data.

- loadThumbnail will skip over broken/unsupported thumbnail data but still
  return 0 in this case.
Merge pull request #355 from lordhoto/skip-thumbnail

TUCKER: Fix for bug #3614697 - "Spanish version uncompletable..."

This add support for the unhandled "mof" instruction present in the
Spanish version. This effectively skips it as a NOP/invalid, which
prevents it locking up the game at the end of the 2nd part.
