Add game description to the quest properties file
Created by: christopho
To be able to display some information about each quest in the Solarus GUI, quest.dat should also contain
- The title of the game (mandatory)
- The author
- A short description of one line
- A long description
- The release date
- Finished or in progress
Also, a quest could have the following optional images:
- quest_logo.png: a 64x32 logo to be displayed as an icon in the quest list. If it does not exist, the Solarus logo will be displayed as a fallback.
- quest_art.png: a bigger image to be displayed in the main area for the selected quest. Size to be decided.
- a few screenshots?
