Updated all sources to current WebGL and TypedArray APIs; WebGLFloatArray -> Float32Array, etc.

Removed illegal enables of state like TEXTURE_2D, LINE_SMOOTH, POINT_SMOOTH, and VERTEX_ARRAY.
Fixed texture wrap mode specifications in ftexture.js.
Changed primitive.compile_program to accept list of attributes to bind.
Enabled OES_texture_float extension at beginning of time because it's required throughout.
Added precision qualifiers to all fragment shaders.
In nurbs.vert, changed outer loops to reference constants, and inner loop to use constant loop bounds and "continue", to match GLSL ES restrictions.
Added missing noisetexture.js from webglot3d project.
