Ars Magica 2 Plant Fix

Under normal circumstances, the plants in AM2 can be found quite easily.  But when used with mods that modify the world generation, the plants may become very difficult to locate.  To solve this problem I created a small mod that allows these plants to be acquired through use of bonemeal on grass blocks.  There are restrictions on where they will appear:

Cerublossom - grass block.  Must be well lit and open to the sky.

Wakebloom - appears on water (not flowing).  Only when dark and must be open to the sky.

Desert Nova - sand.  Must be well lit.

Aum - will only appear under witchwood leaves.

Tarma root - in the dark, on stone (not cobblestone), and under cover.

The base chance of one of the plants appearing is set in the config file.  Defaults at 5%.
