Egg hatching

[Xalcon]

A female chocobo will lay an egg when the mating process is started by using a lovely gysahl green on a male and female chocobo. The egg will be placed as a block.

The first release will require the player to pick up the egg and move it into a nest where it will then hatch into a baby chocobo.

TODO:

• [x] Add hatching logic to the nest TE class
• [x] Redesign Movement Speed Stat scaling. Maybe limit the amount of gain/loss on hatch
• [ ] Allow players to control which chocobo owns a given nest (Using an item?)

In the long run, i'd like to see the mother chocobo to move to the nest, lay the egg inside and keep it warm. This requires a fair bit of AI code and is therefore scheduled for the 1.1 Release.

the chocobo nest owner mechanic will be moved to the 1.0 release since it currently has no use.
