working on creating responsive menu
responsive design now implemented and working
responsive design nearly fully implemented.

testing and implementation of responsive design nearly done. Need to
still work on full post view.
using glyphicon-th for responsive menu
fixed bug with full post view

if a post doesn't have any post images associated with it then the
default image 'no_image.jpg' is assigned to it for use in the view.
edited datepicker to make responsive
added sanitize_array() and sanitize() to helper

sanitize_array() and sanitize work to prevent cross site scripting
