Add search feature via Lunr (see Hugo Learn Theme for reference)

[aral]

The Hugo Learn Theme has Lunr-based search by default. This would be a valuable addition to Cupper and should be relatively easy to port from that theme.

Just a quick update, I have a very basic integration of the Learn theme’s search functionality into Cupper. Doesn’t look good, haven’t had a chance to look into how accessible it is, but it’s there if you want to take a look:

I don’t know if I can keep hacking on this but hope this helps.
