Closes #1251: Add Calibre Web along with a new section for e-books, ILS.

This commit adds the Calibre Web app and positions it inside a new
section for e-books and other mostly text-based media. This is also a
good opportunity to add information about enterprise-class Integrated
Library Systems, so that is done as well and adds the Koha and Evergreen
library management software, both self-hostable Free Software tools to
that category. Koha is moved out of "budgeting," since it is much more
appropriately categorized as an ILS along with Evergreen, et. al.

This commit further moves related items out of Misc/Other, namely COPS,
and into this new e-book/library category, where it should be expected.
