Numerous changes to terrain and trim. The changes to the scneario editor work as expected.

- New way of drawing walkway (doesn't work yet)
- New way of drawing roads (doesn't yet work correctly)
- New way of drawing trim (not tested yet)
- New way of handling marked specials (works in editor but not in game)
- New way of handling two-space rubble in the editor (works as expected)
- Merged several terrain special properties
- Deprecated several terrain graphics
- Completed (probably) the import & convert code for old-format terrain
- Probably other things that I have forgotten that have something to do with terrain
- A few other little things, bugfixes, etc
