chore(gulp): update gulp
fix(images): use ng-src instead of src for image src interpolation
fix(app): silence angular errors by handling references to undefined vars
fix(app): move all config to one file and let the app read config on startup

- It is very cumbersome to configure two or three different files, with
  different variables. So move all the configuration into the
  'config.sample.js' file.
  Users just need to rename the config.sample.js file to config.js and
  put in the requisite data.

- Due to the requirements of templating (making angular read the data
  from the config.js file), using jade for templating.
