Added Local Binary Patterns as filter

-added LBP filters in webgl
-added model with LBP filters
Added switching of filtertypes

Added possibility to switch between Local Binary Patterns,
Sobel/Gradient, and raw filters. Also added possibility to blend or
cycle between the different types of filters in order to improve
precision. Note that this only works in WebGL mode. In pure js mode only
raw filters are possible.
