Bug 11504: Untranslatable "Item Type" or "Collection Code" in branch transfer limits

This patch makes reported strings translatable.

To test:
1. Go to Administration > Library transfer limits

2. Depending on the value of BranchTransferLimitsType
your may see in a box:
a) For *all* Collection codes:
b) For *all* Item types:

change system preference to show both values

3. Update translation files for your preferred language
check new entry
msgid "%sCollection codes%sItem types%s: "

Not pretty but can be translated.

I have to confess that I lower cased the collections and item
types as they appear in a sentence.
No other changes made and this works nicely.
