Release 13 now available

Let's celebrate a new release with an unlucky number, coming with the following improvements:

• 'about', 'credits' and 'help' have now been defined as meta-verbs, meaning they don't increment turns in game when typing them 
• scenery objects now identify more obvious as scenery objects, so that the player doesn't waste too much time bothering with these, other than soaking up the atmosphere they bring to the setting
• a new section to the in-game 'help' as been added, explaining the meaning and mechanic of the manor compendium in detail
• some references and plot hints in the game have been enhanced
• fixed an issue with systems using Ozmoo as an interpreter: Ozmoo's darkmode clashes with color settings when a game makes use of Z-machine colors (like Ghosts does), so Ozmoo's darkmode has now been deactivated, which applies to C64, C128, Plus/4 and Mega65
