Michał W. Urbańczyk 61ce0c915c * "%s substitutions in Right-click information in town hall
* windmill won't give wood
* hover text for heroes
* good background for the town hall screen in Stronghold
* fixed typo in hall.txt
* support for ZSoft-style PCX files in /Data (using SDL_image)
* minor improvements
