Incorporate v3.3 changes

[sshipway]

There is a copy of the v3.3 code, with MSDOS changes, in http://steveshipway.org/software/wanderer/f_wanderer.html -- the README3.3 file explains the changes.

Some of these changes need to be incorporated into the main branch, though none of them are essential.

Everett Kaser's Hero Hearts (which seems to have been based on this game) has these features, as well as the features of version 4.01 as well. Free Hero Mesh (which is a FOSS implementation of the Hero Hearts game engine) also has these features, and it might be possible to implement this game using that engine; the class definitions can be changed as needed in case of any behaviours that do not quite match Wanderer (if you need help, you can ask me questions about its working, or post bug reports and/or feature requests if they are needed).

The Hero Hearts game looks pretty good, with some additional objects and programmable behaviour. I think making a Wanderer-clone in the engine should be possible, as well as all the screens https://www.kaser.com/mesh.html

MESH:Hero engine is limited to 29x21 grid sizes, while Free Hero Mesh has a larger limit 64x64. The screens of Wanderer are too wide for MESH:Hero, but I think they will be OK for Free Hero Mesh. A converter for the screens can be written (the Free Hero Mesh export format can be used).
