ANDROID: Remove parameter forcing use of Modern theme.

This parameter overrides any user choice in the GUI or config file,
which is not good UX design (and is making it hard to debug loading
issues associated with theme files).

If we want to set this to default to Modern, we should do this in
a different way i.e. do this by ConfMan.loadDefaultConfigFile()

This is probably related to the Android issue with the backend init
running before main() is called, rather than after...
MT32: Update the MT32 emulator to a newer munt commit

Previous munt commit was f969d20 (Nov 15, 2012)
Current munt commit is 84b2819 (Dec 22, 2012)

We are still missing the changes from commit 788f7b1 onwards (Dec 22,
2012). There are bigger ROM access-related changes from that point,
which we'll have to integrate as well.
GRAPHICS: Add support for ILBM files containing uncompressed data.

Thanks to Tomaz^ for this patch.
GRAPHICS: Allow ILBM bitmap loading for images with 6 planes.

Thanks to Tomaz^ for this.
VIDEO: Add support for missing copyFrame type in FLIC decoder.

Thanks to Tomaz^ for this patch.
GRAPHICS: Add ability to override outputPitch to ILBM decoder.

This allows loading an image into a buffer of a larger width.

Thanks to Tomaz^ for this patch.
MT32: Update the MT32 emulator and adapt to its new API

Previous munt commit was 84b2819 (Dec 22, 2012)
Current munt commit is 6afddaf (Dec 23, 2012)

This commit also updates the MT32 driver code to the latest munt API
GUI: Redraw the popup widget when a the selection changes

Otherwise, it will look like the value hasn't changed until the
widget is redrawn for other reasons, e.g. by mouse-over.

Incidentally, does anyone know why handleMouseDown() calls
sendCommand() when the selection changes, while handleMouseWheel()
does not?
GUI: Change value by one on mouse wheel, not by one pixel

On file-grained sliders, changing the value by one pixel was
unpredictable because it wouldn't change by the same amount every
time. (And of course, some values were not possible to set.)

On course-grained sliders, changing the value by one pixel would
sometimes not change it at all, causing the slider to seem stuck.

Now the slider can be set to any value.
NEWS: Document slider mousewheel change

It wasn't obvious that the feature was there at all, so now it is
at least mentioned somewhere.
GUI: Notify when popup widget changes by mousewheel

This is consistent with the notification when the widget changes by
clicking. As far as I can tell, that notification was added shortly
before mouse wheel handling was added. It missing from the mouse
wheel handler was presumably just an oversight.
GUI: Don't allow changing disabled popup widgets with mouse wheel

This was another inconsistency between changing the widget by
clicking and changing it with the mouse wheel. Hopefully the last
one, though.
MT32: Move the ROM file deletion code to the ScummVM MT32 driver

This removes the custom ScummVM file deletion code in the munt code
MT32: Add missing initialization code

This code wasn't added when syncing with the official munt codebase
ANDROID: Minor fixes to build-specific makefile.

This fixes two minor issues when trying to cross-compile to Android on
Win32 using the Win32 Android SDK/NDK and MinGW shell.

However, this is still no working as DX and APKBUILDER are batch files
in the Win32 SDK (which then call the real Java tools) and these fail
to run in shell. However, using "cmd /C" also fails as the paths in the
parameters have unix, rather than native separators. Unsure how to fix.

GROOVIE: Simplify the movie speed settings and add a GUI option

This removes the "iOS" speed setting, where some movies could get out
of sync. Two movie options are now available, "normal" and "fast" movie
speed, which is the old "tweaked" setting. With the "fast" movie speed,
the movie speed is changed to match that of the iOS version, but only
in movies with sound. Movies without sound (like the supernatural
animations, i.e. the "teeth" icon in-game) are still played at their
regular speed, to avoid music sync issues.
