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.
Added it into hasFeature() of all engines which returned `true` in
simpleSaveNames() before.
As mentioned in #788, SCI is not always using simple names, so it
doesn't have such feature now.
Engines with "simple" savenames would support "Run in background" in
save/load dialog and gradual save slots unlocking. Other engines
save/load feature would be locked until save sync is over.
- The logo screens of all ITE versions are shown correctly now
- Wyrmkeep versions, demo versions with scene substitutes, demos with
mono music and demo versions with LE VOX encoded voices are all found
automatically now
This includes a renaming of ADObsoleteGameID to Engine::ObsoleteGameID,
and AdvancedDetector::findGameID now is Engines::findGameID.
Doxygen comments were added or improved
This unifies the engine names in MetaEngine::getName() and the
credits. In particular drop "Engine" or "engine" from the names when
it was present and use expanded names in credits when the
MetaEngine uses it (e.g. "Beneath a Steel Sky" instead of "BASS").
MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.
Now AD can search nested directories. By default it is turned off,
but there is new parameter to ADParameters struct. Usually value
of 2 is good enough for all purposes.

- Added two new defines, ENABLE_IHNM and ENABLE_SAGA2 (enabled by default), which can be used to remove the parts of the SAGA engine which are specific to IHNM and SAGA 2 games. Hopefully, this will reduce the size of the engine even more for platforms with little memory (e.g. the Nintendo DS)
svn-id: r35672
- Stopped loading the isomap and puzzle game modules for IHNM, as they are not used for that game (this saves some memory for IHNM)
- Removed getDisplayWidth() and getDisplayHeight()
svn-id: r35473
- Added a new method to the MetaEngine class, getMaximumSaveSlot(), and implemented it in all engines for which the listSavefiles() method is implemented (it goes together with the listSavefiles method). It is used to fill the unused save slots in the save/load dialogs of each engine, so that the user can create new save games in empty slots
- Unified the save/load dialog list numbering in the GMM load/save screens and in the load screen of the main menu (before a game is started)
