Commit Message:
TINSEL: Show saved game creation time in load/save gui

Saved games inspected via the ScummVM load or save
gui will now show the year, month, day, hour, and minute
of its creation. This was already being saved in the
saved game header so no version bump is necessary.

This required adding kSavesSupportMetaInfo and
kSavesSupportCreationDate features. I also had to
add kSavesSupportThumbnail or the saved date is not
shown.

It was necessary to write querySaveMetaInfos.
