Currently, the BookManager extension uses the values of the following messages from [[mw:Extension:Collection]]:
- [[MediaWiki:coll-collections]]
- [[MediaWiki:coll-community_book_prefix]]
It should have its own messages, whose default values should be those defined for Collection extension (after testing if Collection extension is available). This way BookManager would not break unexpectedly if collection extension is not installed.
