Sphinxsearch ready

[nurse-curtis]

I don't expect this to get pulled in (I'm a git novice), but thought it might at least bring to your attention in case it helps, since your repo has saved me, and many others I'm sure, tonnes of time. Shouldn't add much overhead if not used, but is simple to setup if one is so inclined.

I added the sphinx package and made it run using the default sphinx.conf in nZEDb, so the paths do vary a bit from the Alpine defaults. Added a supervisor script, and changed the setup_data_dir script to account for this so there is a log file and directory to keep the Sphinx index.

From there, it is just a matter of following the README.md in sphinxsearch directory.

I've never used the sphinx integration so I'll try to check it out when I have time.
