commit fd6c540b6faa6c802c92c9e209e2122ca3ddfa92
from: Omar Polo <op@omarpolo.com>
date: Mon Feb 12 15:51:59 2024 UTC

add cmd_search to search using a search engine

This adds a new command `search', bound by default to `s', that
prompts for a query and loads and consult the ``oracle'' (the search
engine) using default_search_engine (which will be made customizable.)

It also temporarly supports only gemini URLs.

Feature requested by -fab-, thanks!
