Updated mediawiki/extensions
Project: mediawiki/extensions/BookManagerv2  e8f9546a81b075dede604d4be6747b502c252211

Use the wiki DB for the BookManagerv2DBname.

Previously the DB name was hardcoded in, but this required
any wiki to have a DB named "wikidb". Now the extension
just gets the name of the wiki's DB when necessary.
