Comment 7 for bug 1711128

Here is a branch that adds a distinction between simultaneous use and cost per circ titles as noted by Jeff in comment #2. Simultaneous use titles will display "Always available" while cost per circ titles will display "Limited availability." I'm not sure that language is meaningful to patrons but that is the language Overdrive uses. Input from someone with cost per circ titles appreciated.
