Added 1 Creature for Each Room

Added 5 creatures to the map as well as a point light for each to make
them more visible. Important to keep in mind that just because the walls
are white, that does not mean they are light sources (without these
point lights, the creatures are very dark). A more long term lighting
solution will be necessary.

Each creature has it's own folder in Assets\SporeCreatures . The
preconfigured creature can be found at the root level (it doesn't have
the light attached, but does have its diffuse and specular maps). In
each Components folder is the lower level content for constructing the
creature.
