added a blue tiberium blossom tree.
Gave blue tiberium blossom a sequence; changed #2

Blossom tree has a sequence. 
There are two blossom trees in C&C, so I will use the first one (split2) for green tiberium and the 2nd one (split3) for blue tiberium. The old split3 still exists for backwards-compatibility, but will now show the split2 image. Only the blue tiberium blossom tree will show the split3 image.
