For every subject s, please add "s: All" as an entry in the subject drop down.

When we click on the 'search books' box, show all the ": ALL" entries on top in alphabetical order. So, if we add javascript documents to the current set of documents, we should see 'Javascript Doc: All' followed by 'Python 3 Doc: All'.

When user types letters in the 'search books' box, we show all books that match with the letters typed. Going forward, please ensure the top entries are ":All" entries. So, if user types p, we show 'Javascript Doc: All' followed by 'Python 3 Doc: All'. When user types py, we show 'Python 3 Doc: All' followed by all the Python 3 documents like Tutorial, Lib ref etc.

If user selects "s: All", the books part of the URL should become 's*'. If user selects "Python 3 Doc: All", the books part of the URL should become 'python-3-doc*'.
