Changed appearance of close button on (large) dialogs back to original.

Removed explicit SDL dependency in game.

 ```
 
+If you want to use the Allegro backend you can add the build tag `allegro` to the `go install` command. E.g.:
+```
+go install opslag.de/schobers/tins2020/cmd/tins2020 -tags static,allegro -ldflags "-s -w"
+```
+In this case the SDL 2.0 prerequisite is replaced by the Allegro 5.2 (development libraries must be available for your C compiler).
+
+## Command line interface
+You can extract all resources embedded in the executable by running it from the command line with the `--extract-resources` flag. The resources will be extract in the current working directory. Note that the game will use the resources on disk first if they are available.
