Fixup for Hunted.

Took out a few unneeded globals, seperated Fortress Point rewards from
the Team Points globals, made Quad Damage attach to Umbrella weapon
rather than Hunted player (so other weapons used by the Hunted will not
trigger Quad Damage) and took out a lot of unneeded gaps.
Radio-Tag On Damage and Hunted Weapon Choice added.

Option to Radio-Tag the Hunted when he takes damage and choose what
weapons the Hunted gets on spawn.
MarkRadioTag uses player who tagged.

Requires ddm999/fortressforever/better-markradiotag.
