Fixed a major issue where all EVT layers were returning an evt of 0 due to the layers not storing their data in the floatdata1 field.
Implemented several fixes and optimizations in forest generation. The world shouldn't be so barren with only occasional redwoods anymore. Added a StopWatch helper class for timing things when needed.
