If the user enters in an invalid description for the save then it will be
simplified by the saved name cache process in Script::savegame.
I checked this with t7g, but not with the 11th guest or any other Groovie game.
The original in-game loading/saving can still only access the first 10 save
slots (0-9).
Its possible to saving via the GMM when the game is interactive.
Loading a game saved via the gui using the original in-game load menu
works fine.
Saving via the GMM with timestamp works, but only only saves the characters
up to the first non-alpha non-letter characer.
Now SaveStateDescriptor no longer subclasses HashMap. Instead all possible
saved meta data is included directly into SaveStateDescriptor.
This is slightly less flexible, but we never needed that flexibility so far.
On the other hand it should reduce the memory usage. At least on my system
(Linux/amd64) the old SaveStateDescriptor had a size of 928 and the new
SaveStateDescriptor has a size of 200.
