This commit introduces the following changes:
1. Graphics::loadThumbnail()
Now returns a boolean and takes a new argument skipThumbnail which
defaults to false. In case of true, loadThumbnail() reads past the
thumbnail data in the input stream instead of actually loading the
thumbnail. This simplifies savegame handling where, up until now,
many engines always read the whole savegame metadata (including
the thumbnail) and then threw away the thumbnail when not needed
(which is in almost all cases, the most common exception being
MetaEngine::querySaveMetaInfos() which is responsible for loading
savegame metadata for displaying it in the GUI launcher.
2. readSavegameHeader()
Engines which already implement such a method (name varies) now take
a new argument skipThumbnail (default: true) which is passed
through to loadThumbnail(). This means that the default case for
readSavegameHeader() is now _not_ loading the thumbnail from a
savegame and just reading past it. In those cases, e.g.
querySaveMetaInfos(), where we actually are interested in loading
the thumbnail readSavegameHeader() needs to explicitely be called
with skipThumbnail == false.
Engines whose readSavegameHeader() (name varies) already takes an
argument loadThumbnail have been adapted to have a similar
prototype and semantics.
I.e. readSaveHeader(in, loadThumbnail, header) now is
readSaveHeader(in, header, skipThumbnail).
3. Error handling
Engines which previously did not check the return value of
readSavegameHeader() (name varies) now do so ensuring that possibly
broken savegames (be it a broken thumbnail or something else) don't
make it into the GUI launcher list in the first place.

- Save scene parameters before playing a movie and restore them afterwards (fixes crash)
- Fix text disappearing too fast
- Implement script function sfGetCameraChanged
- Replace nop script functions with stubs which print debug info when called

- Fixed return values in savegame/loadgame
- Some minor cleanup

- Loading/Saving during run time
Other savestate functions yet todo.
I'll probably remove the "original" in-game menu and move everything to the GMM.

- Optimized drawing code; now only items (sprites, text, screen masks) which have changed from the previous frame are redrawn, this speeds up things a lot
- Implemented dirty rectangles using a microtile array
- The previously committed Microtile Array implementation from SEL seemed buggy so I wrote my own version which works nicely so far (and is less code and GPL), only MicroTileArray::getRectangles uses parts from the old version, this will be changed later
- One known bug related to dirty rectangles remains: Sometimes the background isn't restored correctly and gfx artifacts are visible

- Kernel function 5 returns a random value; use ScummVM's RNG

|
- Save/load mouse position and if the cursor is enabled
|

make debugging somewhat easier.

- Beginnings of the saveload system (incomplete)
