#12 Old style /fg switching

[RPhillips]

This is a patch that gives an additional flag variable: oldstyle_fg

If applied set, tf-50b8 will do oldstyle world switching, where it just shows the ---- world ---- name, and the new text; without clearing the screen (like tf4).

Example:
/set oldstyle_fg=1

Instructions:

1) Copy the patch file into your tf-50b8 folder (where you would normally type ./configure)

2) Go into your tf-50b8 folder and test the patch file: patch --dry-run -p1 -i oldstyle_fg.patch

If you get output like:
patching file src/output.c
patching file src/socket.c
patching file src/varlist.h
.. then everything is set.

3) Apply the patch: patch -p1 -i oldstyle_fg.patch
