Bug 11649 - Always use words "copy number" - intranet

In most cases, the value of items.copynumber is displayed using the
words "Copy number". But in some cases, it is just "Copy".
It would be better to always use "Copy number" because in translation
the word "Copy" means the action of coping.

This patch manages templates of intranet.

To test, display an item containing a value in items.copynumber.
