Create fishing worker

[krazyjakee]

Each map should have a fishing worker.

The fishing worker should load each water source.

While a player has cast, a timer should tick for that water source so that each second there is a chance that the player will catch a fish. This is based on the fish chance but rod, tackle and bait chances can be used as modifiers. The fish weight should also be calculated.

If there is a catch, the player inventory should be updated and a message send to the client.

If a player uses bait, it should affect the whole water source for a period of time.
