Enable analog joystick support.

I've split and enhanced this patch.

This first one, enableanalogjoy.diff, re-enables using analog axes from the
joystick, instead of converting them into keyboard commands.  This is tied to a
new cvar, in_joystickUseAnalog.

Just applying this patch exposes a couple of bugs.  First, the forward and back
directions are reversed, and second, the sensitivity is way too high for yaw.

The second patch, customjoyaxes.diff, solves those bugs, uploading after this.

Add customizable joystick axes

The second patch, customjoyaxes.diff, solves those bugs, by adding additional
cvars, since there are no guarantees where and in what direction axes go in
SDL.

These cvars are:
  -j_forward, analogue to m_forward, for forward movement speed/direction.
  -j_side, analogue to m_side, for side movement speed/direction.
  -j_pitch, analogue to m_pitch, for pitch rotation speed/direction.
  -j_yaw, analogue to m_yaw, for yaw rotation speed/direction.
  -j_forward_axis, selects which joystick axis controls forward/back.
  -j_side_axis, selects which joystick axis controls left/right.
  -j_pitch_axis, selects which joystick axis controls pitch.
  -j_yaw_axis, selects which joystick axis controls yaw.

After this, 360 gamepad support is almost complete, except for the weirdness
with the left and right triggers being the same axis.  That can be fixed by
changing one line after applying the first two patches:

sdl_input.c, line 810:
            if (!in_joystickUseAnalog->integer)
to:
            if (i == AXIS_UP || !in_joystickUseAnalog->integer)

which changes the Z axis into keys.

Cool, will look at this later.
