Cleanup in webgl code

-changed uniforms to consts in shaders
-changed loop counter to int to avoid floating point troubles
-cleanup
Optimized webgl code

-minimized texture reads by removing a loop in the patch shader
-minimized texture reads in sobel shader
Removing antialias in webgl

-Unnecessary antialising causing bugs in some browsers
-rebuilt clmtrackr.js
Removing antialias in sobel webgl

Forgot to remove antialias in sobel webgl code as well
Added fallback when webGL setup fails

-added fallback to pure javascript when webGL setup fails. This happens
on IE11, since webGL shaders used here are too complex.
Rebuilt clmtrackr.js and clmtrackr.min.js
Added error message for face_deformer

-Added error message for face_deformer when webGL setup fails
Fixed html5 file-support issue in clm_image.html

-dropped checking for FileError, since it's not needed and IE11 doesn't
support it
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.
Test of adding bias in webgl shaders
Rebuilt models

Rebuilt models and removed webgl-version with adding bias in shaders
Rebuilt clmtrackr.js and clmtrackr.min.js
Switched back to jsfeat Haar face detector

Switched to jsfeat Haar detector instead of ccv due to better detection
in jsfeat
-fixed small bias-error in fft svmfilter
Removed ccv.js and rebuilt clmtrackr.js

-Rebuilt cmltrackr.js
-removed ccv.js from examples, readme and gruntfiles
Link to clmtools in readme
Fixed better scoring of faces

-better scoring in general
-wait for  scoring before convergence
-changed scoring to SVC, cropped down face window, changed mean/variance
normalization and log preprocessing
-new scoring in models
rebuilt clmtrackr.js

+cleanup
Added links to new demos
correct triangle height calculations
previously the "y" offset was not being calculated so this was added. Also added interspace to avoid mixing border pixel values from surrounding patches.
