Update our social media script

Please update our PHP social media script to work with Tumblr and Facebook. The script currently works for Twitter. So this should be duplicated for Tumblr and Facebook. 1. I need the "follow user" function in the script to be for Tumblr so the "follow user" function should work as normal for twitter then connect with the tumblr API specs I have. I also need to copy the unfollow that is done for twitter also 2. I need the "follow user" function in the script to be for Facebook so the "follow user" function should work as normal for twitter then connect with the Facebook API specs I have. I also need to copy the unfollow that is done for Twitter 3. Unfollow for Twitter, Tumblr, and Facebook should be based on when I made the request instead of a set number of days to unfollow
