Borrowings fragment

Removed the test fragment and replaced it with a borrowings fragment.
Changed so that apihelper get function returns JSONTokener. Added Loan
and Reservation classes to parse api calls. There are functions for
getting current users loans and reservations. Apihelper now supports
delete calls. Still some things left for the borrowings fragment.
Borrowings fragment

Fixed so that button works within the listview. Listview now handles
clicks and sends the title id to the MainActivity. TODO: Wait for the
title page to be finnished and send the id to that fragment.
Borrowings fragment

Added real icons, replacing the placeholders. There are special icons
for when a loan is recalled and when a reservation has a loanable
available. Also the background for those items are set. Date is shown
without time. Toast when checking in. TODO: Set TextView when no items
are available / no internet.
