Bug 11357 - biblioitems.size value not correctly displayed in list emails sent from OPAC and intranet

The size column in biblioitems is a bit problematic when used in TT, because instead of the size value from the biblio column it will give you the size of the variable.

It's currently used in the templates for sending shelves from OPAC and intranet and maybe also in other places:

[% END %]
   [% IF BIBLIO_RESULT.size %]
   , [% BIBLIO_RESULT.size %]
[% END %]

This patch corrects by using item() TT method.
See http://stackoverflow.com/questions/2311303/how-can-i-handle-hash-keys-containing-illegal-identifier-characters-in-template.

Test plan :
In each display :
=> Without this patch you see biblioitems.pages and then a number
=> With this patch you only see biblioitems.pages

- Create a record with biblioitems.pages defined (like "12p") but without biblioitems.size defined
Same for OPAC and intranet :
- Add it to the cart
- Open the cart
- Check the "Title" column
- Click on "More Details"
- Check the "Details" row
- Send the basket via email and check the result
- Add to a list
- Send the list via email and check the result
