New option file to create a multiple selection field for books,
this then allows one to select what types of books should be processed.

However by it self it is only a new version of options that supports the multi
monkey.
Include the new multiselect funtion in the list of functions
Theme changes to display the new multiselect box for book types
This affect the site_edit screen so that the multibox both works and can store the values to the sites table.

Since sites only stores single values and this is a list we need to convert back and forth which makes up much of the code.
Finally convert books from using a static list to a list generated from the sites table.  1 new varaiable and then convert the static in clause to a dynamic one.
a few more fixes for the query and a sanity check so that if the new
multiselect was not used yet or has nothing entered the behavior is
the same as before.  This should make upgrading to the new method
safe.
