Add Gen IV honey tree encounters

[Machine-Maker]

Change description

Add honey tree encounters to Gen IV games.

Added 7 slots per vg, 1-6 either have honey-tree-group-a or honey-tree-group-b as condition, 7 has 100% chance with honey-tree-group-c. Descriptions for each encounter condition value say 70% on group a for non-munchlax trees, 20% for munchlax-trees. B and C say correct respective chance.

Added 1 new location area, floaroma-meadow-area which didn't exist before because there aren't any pokemon encounters except Honey trees.
