Summary: Headless Support Patch

Initial Comment:
There are three classes in src/bzflag which
unnecessarily assume that they are being used in a
graphical context.  With a very small patch we can
remove this assumption.  In the attached patch, we add
"extern bool headless;" in playing.h and use this
variable in Player, LocalPlayer, and
SegmentedShotStrategy to protect parts that assume
graphics are available.  Fortunately, there are very
few such areas.

Since headless=false by default, nothing is changed
under normal bzflag operation.  However, being able to
set headless=true is very important when operating
without a graphical display.

In the long term, it would probably be best to move the
graphics code completely out of the three affected
classes, but the attached patch seems like a good
solution for now.  If nothing else, it makes it clear
where the trouble areas are.
