remove unnecessary casts and tests for null, discovered using NetBeans (#1285)

* remove unnecessary tests for null, discovered using NetBeans

* jme3-core: remove unnecessary casts

* jme3-examples: remove unnecessary casts

* jme3-vr: remove unnecessary casts

* jme-plugins: remove unnecessary casts

* jme3-terrain: remove unnecessary casts

* jme3-desktop: remove unnecessary casts

* jme3-android: remove unnecessary casts

* remove unnecessary casts, discovered using NetBeans

* TerrainQuad: back out one casting delta that's not a removal

* TerrainPatch: simplify generateLodEntropies() after removal of the cast

* TerrainPatch: simplify reIndexGeometry() after removal of the cast
