Summary: roaming for observers

Initial Comment:
This patch enables roaming for observers. Roaming is a
feature which allows you to watch a game of bzflag from
an arbitrary position.  It has always been part oz
bzflag but wasn't enabled by default. Now, with
observers, it becomes a very useful feature. With this
patch, an observer will be in roamign mode always,
whereas a normal player will not able to use roaming.

I also changed the keys used for roaming and added some
features:

There are 4 roaming modes: free, tracking, following
and first person view:

Free mode lets you move your camera freelyin 3D space.
This is done using the cursor keys. Left and right
cursor will roatte the camera, cursor up wil tilt it
down, and cursor down will tilt it up. If ou hold
shift, the cursor keys will move the camera to the
left, right, forward and back. If you press hold alt,
cursor up and down will move the camera up and down,
respectively.

By pressing F8, you can change the roaming mode to
tracking. In this mode, you can still move your camera
freely, but it will automatically look at the targeted
tank. F6 and F7 will cycle through all possible targets
(tanks).

Pressing F8 again will enter follow mode. Here, the
camera will be following  a tank closely.

One more press on F8 finally goes into first person
mode. Here the camera will be positioned inside the
tank, so you'll get a first person view.

Pressing F8 then returns you to free roaming mode.

I also changed the HUD to display differently in
roaming mode. It will now say that you are roaming or
tracking which player.


Roamign isn't perfect with this patch, there is still
much room for improvement (camera should have some
inertia to avoid jumping, usign the mouse to rotate
camera would be nice). But it's definitely very nice
when observing.

This prolly works.

void TankSceneNode::setHidden(boolean _hidden)
{
  hidden = _hidden;
  if (hidden)
	invisible = False;
}

Chestal,

  Roaming code added a bug, that you can now see any 
cloaked player (whether or not you're in roaming mode).

Playing.cxx line 4038


	// add other tanks and shells
	const boolean colorblind = (myTank->getFlag() == 
ColorblindnessFlag);
	for (i = 0; i < maxPlayers; i++)
	  if (player[i]) {
	    player[i]->updateSparks(dt);
	    player[i]->addShots(scene, colorblind);
	    player[i]->addPlayer(scene, colorblind, True);
	    player[i]->setInvisible(player[i]->getFlag() == 
CloakingFlag);
	    player[i]->setHidden(roaming && roamView == 
roamViewFP &&
	                         roamTrackTank == i);
	  }

--

setHidden turns invisible OFF

maybe do 
setHidden before setInvisible
