Install solr extension from source

[stronk7]

Using 2.4.0 release + custom patch (from macports project) seems to
be the only working combination right now. Read the comments in the code
and the links there.

Resolves solr issue in #16, waiting for the upstream as described in #19

I'm really not keen to add yet another script into root/tmp, but I already have a separate issue to get rid fo them all.

They are a really bad thing and against docker's recommendations for building images and we need to get rid of them.

Yeah, I agree. Just thought that it would be easier to continue with the current status/style until we reconsider all the branching/directories/style thing. But agree we should move out from scripts as much as possible (not sure how much that "as much" is, lol).

Ciao :-)
