Environment and DeadOrganism

Renamed Environment to BioEvolveEnviroment in order to differentiate
between application environment and the environment local to my app.
Organisms can now die. Added humidity and AbiogenesisRate properties to
Environment. Created constructors for tiles, environment, and dead
organisms.
Finished Binding

Bound sliders on the GUI to the current environments humidity  and
abiogenesis rates. Added an 8bit grass texture to environment
tiles....may change.
Added dependency properties for Tile gui

Water and fertility levels were changed into dependency properties to
provide the ability to right click and display the values of the tile.
Added functionality to change the tile's water and fertility levels.
Added group boxes to selected objects on the map grid. The tile selected
groupbox is implemented, but the organism selected group box is not.
