Add borrower

This is the stuff I did in the evening. It contains a new modal box for the add borrower functionality.  It desperately needs refactoring ans there is a lot of duplication but it is not possible to easily do this without access to working apis.  Most of the code is in the app.js file and a little in the .html file.  Feel free to pull it down and check it out in the morning before i get in if you want to.
