Adding WebGL version of the trends demo, including the original and new particle versions. Differences in the non-particle version:

* Switched the created energy texture from 3x32 (NPOT) to 4x32; made the energy shard width smaller.
* In the shaders, added abs before the sqrt call to normalize behavior across CG/GLSL.

Translated GLSL shader string in particles.js to be more human readable.
