Rarity / fertility tweaks for various mods (#8)

Browse Source 
For bushes, molehills and youngtrees:
Changes to rarity and minimum fertility. Also added use of rarity_fertility. Result is more balanced and less homogeneous, i.e. over a large area you'll see variation.

For vines, some further tweaks to rarity, and using tries field to improve vines distribution.
