 === Savegames ===
-* Added error return codes to openForSaving / openForLoading so that client code can nicely detect & report save/load failures ("media full", "file not found", "save path does not exist", "save path not writeable", etc.).
-* Try to get rid of getSavePath(): It is mostly used to print out more meaningful error messages about save failures. Instead of that, consider adding a getLastError() or so call, which return a string with additional information about the error. This is more portable, too.
-* <p>Let me give a specific example on how error handling could look like:
-<pre>
-ErrorCode err = saveMan->openForSaving(name, &myFile);
-if (!err) {
- myFile->write(...);
- ...
- err = myFile->ioError();
-}
-switch (err) {
-case kNoError:
-  break;
-case kMediaFullError:
-  display("Writing your save game failed due to lack of space: %s", saveMan->getErrorString());
-default:
-  display("An error occured while writing a savegame: %s", saveMan->getErrorString());
-}
-</pre>
-As a slight variation, we could introduce an "error manager" which offers the "getErrorString" method and which could be used by more code. Compare also with SDL_SetError & SDL_GetError.
