RFC: Add a search option

[carstene1ns]

Will be useful later for the (static) blog and wiki.

Search is running on the client. Data is preprocessed by nanoc.
This makes it fast and not resource hungry.

I have added the whole blog locally and the json data is still smaller than one screenshot... ;-)

You can try it here: https://ci.easyrpg.org/job/website-pr/ws/output/search/index.html

The links are broken, since i do not add the (changed) base-url. This could be fixed later.

https://ci.easyrpg.org/job/website-pr/ws/output/search/index.html?q=player -> even permalinks work.

Rebased on the netlify PR.

This works pretty well imo 👍 . Wouldn't have expected that searching can be possible on a static page.

Only thing missing is a way to reach the search.

A later PR could also add a preview feature to indicate where the search result was found with adjacent text for context

[carstene1ns]

Should be more visible now.

Was there anything missing here? I simply forgot about it. 😅

Only change I would suggest is moving the search icon into the header after "Contact" because currently it is not possible to search while on the main page.
