a cute metasearch engine

it sources from google, bing, brave, and a few others.

it's written in rust using no templating engine and with as little client-side
javascript as possible.

metasearch2 is a single binary with no cli or configuration file. if you want
to configure it (like to change the default port or weights of engines) then
you have to modify the source.

build it with `cargo b -r`, the resulting binary will be in
`target/release/metasearch2`. it runs on port 28019.
