#Gulp Global Exclude
Add exclude patterns to gulp that will be used in every .src and .watch call.
Usage:
var gulp = require('gulp');
var globalExclude = require('gulp-global-exclude');
globalExclude(gulp, ['!node_modules/**', '!build/**']);
Now '!node_modules/' and '!build/' will automatically be appended to the
patterns array in any .src or .watch call.
