Better separate VaultWiki and rest of forums
I know some people want a tighter integration of VaultWiki with the regular forums - using VaultWiki bbcodes and templates everywhere, etc. I guess it's the reason for any forumdisplay page to include 4 VaultWiki .php files. And any showthread page _always_ includes the whopping 8 VaultWiki files, totalling 9000 lines as of 3.0.0 RC3!
However I suspect many are also not interested in using Wiki's templates or its other features in the regular forums (we don't need it, for example). Maybe make the integration optional via the settings and save the page processing time for those not needing the close integration?
On a related note, the fetch_threadinfo_query plugin unconditionally JOINs two additional VaultWiki tables - is it really always necessary? What are they used for on the non-Wiki showthread pages?
