-------------------------------

-- CTF_BLIZZARD 0.9

--------------------------------

---------

-- 0.2

---------

-- disabled super weapons

-- theme modifications

-- improved hog placement system: teams can now be put

---------

-- 0.3

---------

-- In this version:

-- changed starting weapons

-- changed crate drop contents and rate of drops

-- completely removed super weapons and super weapon scripts

-- removed custom respawning

-- removed set respawn points

-- added AIRespawn-esque respawning

-- added simple left vs right respawn points

-- added non-lethal poison to flag carriers as an indicator

-- improved flag mechanics and player-flag feedback

-- flag now instantly respawns if you kill enemy hog and return it,

-- or if the flag falls in water, _BUT_ not if it is blown up

---------

-- 0.4

---------

-- tweaked crate drop rates and crate contents

-- improved the teleporters, they should now be able to handle rope... hopefully

-- updated SetEffect calls to be in line with 0.9.15 definitions

-- added visual gears when hogs respawn

-- added visual gears when hogs teleport

-- added visual gear to track flag and flag carriers

-- removed poisoning of flag carriers

-- removed health adjustments for flag carriers due to aforementioned poisons

---------

-- 0.5

---------

-- added translation support, hopefully

-- added ctf rules

-- added effects to the teleporters

-- added aura round spawning area

-- changed the aura around the flag carrier / flag to an aura and added some support for this

-- changed things so the seed is no longer always the same...

---------

-- 0.6

---------

-- removed branding and version number

-- removed teleport from starting weapons

-- increased captures to 3

------------

-- 0.7

------------

-- hopefully fixed a bug with the teleporters

-- added a fix for crate possibly getting imbedded in land when it was near the water line

------------

-- 0.8

------------

-- fixed version control fail with missing check on onGearDelete

-- changed hog placements code so that they start in the same place for both teams

-- and hogs move in the same order, not backwards to each other.

-----------

-- 0.9

------------

-- add support for more players

-- re-enable sudden death, but set water rise to 0
