[Bazaar] Improve Bazaar Search Performance (#4615)

Browse Source 
* Create Alternate BazaarSearch Routine

Establishes an alterative to the in memory bazaar search routine and instead uses a db query process.  For large Bazaars (with 1000s of items) this is much faster.  Testing with 30k items produced a search in ~1sec version 2.7sec for the in memory version.
Default is false - Do not use this version.

* Indexes for trader and items

* Set query-based bazaar search the default

* Update database_update_manifest.cpp
