Bug 30937: Add a detail view for libraries

This patch adds a view page for libraries, so that the user isn't
required to edit the library to see information about it.

To test, apply the patch and log into Koha as a user with permission to
manage libraries.

- In the list of libraries you should see that the library name in the
  first column is now a link.
- When you click the link you should be taken to a view of all the
  information about the library.
