Title: Adding backwards history search

I've added 'The most useful thing in bash' from https://coderwall.com/p/oqtj8w

This allows you to search through your history using the up and down arrows … i.e. type "cd /" and press the up arrow and you'll search through everything in your history that starts with "cd /".
