HOPKINS: Rework Credits (WIP)
TONY: Fixed scripted exit to use engine method, rather than error().

This fixes bug #3586252 ("TONY: Game errors out when exiting via the
menu").
VIDEO: Clarify some VideoDecoder documentation
SCUMM: Hopefully fix warning

Excplicitly cast to int to avoid a warning that I don't get, but
which clone2727 does. At least, I hope it avoids the warning.
SCUMM: Try harder to open the Loom Macintosh executable.

Try the Mac OS Roman form, the UTF-8 form and the filename without
any trademark glyph.
SCUMM: Move Mac player initialization to its own function

Apparently we cannot (portably) call virtual functions from the
constructor, so initialization has been moved to a separate function.
CONFIGURE: Force static build when crosscompiling for AmigaOS.
SCUMM: Remove Mac version of MI1 from special case.

We no longer use iMuse for MI1 Mac so this never happens. The Mac
player can only play one song at a time, so it should be all right.
HOPKINS: Finish work on Credit
HOPKINS: Fix exit in full game
VIDEO: Improve a Cinepak heuristic

Brings it inline with the FFmpeg/libav version again
README: Mark only the DOS EGA version of Loom as skipping copy protection
MT32: Update the MT32 emulator to the latest munt revision

Previous munt revision was 189f607c88e7404ad99abcf4b90f23b103003ed1
(Feb 09, 2012).
Current munt revision is f969d2081d41b669c1bfebd0026b5419c09517ae
(Nov 15, 2012)
DREAMWEB: Add an extra line showing the available terminal commands

This is possible, since the game is freeware now. It is very
helpful when playing the game in order to avoid referring to the
manual. The extra help text is shown when the player uses the
'help' command inside the game terminal.

Also, the list of games where copy protection is skipped has been
reordered alphabetically in the README
HOPKINS: Add some more code specific to the full version (linux)
MT32: Make all constant tables in the MT32Emu namespace static

Added in munt commit d4f8ebf54be0a8255af08bb24f1962afa8378096
SCI: Properly reset the palVary signal when loading (bug #3575569)
README: Change wording of the Kyrandia walkspeed setting to "number"

This is changed from "int" to "number" for uniformity with the rest
of the game options (plus, "number" is better understood by
non-programmers, whereas "int" is more cryptic)
README: Describe "walkspeed" for Kyra2+Kyra3.
README: Break some lines on 79 characters again.
