Instructions for setting up local MediaWiki with practicalplants format

[petteripitkanen]

For building and testing a practicalplants wiki integration for powerplant, create instructions for setting up a local MediaWiki with practicalplants format. Note that there are dumps available that have been created with the WikiTeam tools, and it should be possible to import these to a MediaWiki instance by following this.

Leave a comment here with more fine-grained instructions for your environment, we can then think of creating a wiki page on github for documenting the process.
