Bug 5652: display subtitles on patron checkout and holds summary

This patch adds subtitles (from Keyword to MARC mapping) to the
following tables on the checkout page:

- Checkouts
- Previous checkouts
- Relative's checkouts
- Relative's previous checkouts
- Holds

Additionally it suppresses the appearence of the superfluous word "by"
in cases where the biblio has no author.

Test scenario:
--------------
1)
Make sure that you have one or more fields mapped to subtitle in:
Home . Administration . Keyword to MARC mapping
(e.g. 245 b)

2)
Test the checkout page with patrons having
- current checkouts (today)
- previous checkouts
- relatives (e.g. kids) with current /previous checkouts
- holds on items
- holds on biblios

...with items having:
- title, subtitle, author
- title,  no subtitle, author
- title,  subtitle, no author
- title, no subtitle, no author

3)
Do the same on patron's detail page

Bug 5652: (follow-up) include subtitle in hyperlink

This follow-up patch makes the subtitle part of the same
hyperlink as the title, maintaining consistency with other
pages in the staff interface such as list contents.

To test:

[1] Make sure that the Keyword to MARC mapping includes
    mappings to 'subtitle'.
[2] Find a biblio that has both title and subtitle.  Check
    it out to one patron and place it on hold for another.
[3] In the checkout and patron details pages, verify that
    the entry for this bib in the list of checked out titles
    or hold requests includes both title and subtitle in
    the same hyperlink.

Bug 7257: Add a link to remove an individual title from a list in the OPAC

It should be possible when viewing the contents of a list to click a
link to remove an individual title from the list without having to check
a checkbox and click another button.

This patch adds a link to each list item to "Remove from this list."
The functionality is JavaScript-dependent, automatically checking the
appropriate checkbox and submitting the form to delete.

To test, view a list for which you have delete permission. There should
be a "Remove from this list" link next to each item on the list. Test
delete functionality by:

- Clicking the link and then clicking cancel.
- Clicking the link and confirming.
- Checking more than one checkbox and then clicking a single remove
  link (only the one corresponding record should be removed).
- Checking one or more checkboxes and clicking the "Remove from list"
  link at the top of the page.

If JavaScript is disabled the links should not appear.

There are now two delete confirmation messages: One if you're removing
only one item, another if you're removing more than one. This is true
whether you use the links or the checkboxes.
