Kika Clouds Gatekeeper

[AntumDeluge]

Adds a "gatekeeper" for requesting entrance to Kika Clouds.

The problem: Due to the nature of the Kikareukin Clouds zone, players are tempted to camp in Kika 6. Following are some of the factors that contribute:

• some uncommon or rare creatures are found there
• some uncommon items can be gained from killing creatures
• a substantial amount of money can be gained from killing creatures

Similar to camping issues that came about with the hell zone, it makes it unfair to those that are playing the game more casually (e.g. not camping all day in an area to get creatures before anyone else can). However, the method introduced with the hell timer should not be used for Kika. The problem with doing that is that players who are not camping risk the same as those that are. The solution should have little to no affect on casual playing.

Some methods have already been implemented to attempt to prevent camping Kika 7. A timer was introduced that ejects the player after it expires. And, a cooldown period was added where if a player re-visits the clouds within that period their time to stay on the map is shortened significantly. While these have helped, they have not made enough of an impact as needed to make the game fair for all players. Players are still found to keep their characters in Kika 6 & login every 6 hours to check the clouds.

The solution: The additions in this pull request help by creating at least a 24 hour window in which camping players cannot visit the clouds. This gives more of an opportunity for creatures to respawn & for other players to have access to them. The features included are a "gatekeeper" that tracks the number of requests a player makes to enter the clouds. Players can still visit multiple times in a single day. However, they cannot visit more than 3 times within a 4 day period. Attempting to do so uses up the balloon, just as if they had been granted entrance, but does not teleport them to the clouds. Not changes are made to the timer that dictates how long the player can spend in the clouds, nor are there any changes to the cooldown period for re-entry.

TODO:

• if a request to enter is made during the cooldown period (6 hours?) after visiting Kika 7, it should not count toward number of requests as player cannot spend the full amount of time in the clouds anyway
• remove XP loss punishment
• remove HP loss punishment
• remove sent to afterlife punishment
• change message from gatekeeper to reflect above changes
• add event with visual & audio effect (lightning & thunder) (web client only)
• add sound to symbolize balloon popping
• add one-time notice about potential rejections in the future

Result of rejection:

• sent to afterlife (removed)
• HP set to 1 (removed)
• loses 15% of excess XP (removed)
• negative karma
• balloon not retained (e.g. balloon is used the same as if entrance was allowed)
