Since rayhunter is getting more popular let's set some expectations
around pricing. There are currently offers ranging from 20 to 90 USD,
and people should understand that the 20 USD offer is not a fake, or
anything like that.
* Add a new configuration page and move content out from TP-Link. The
Configuration section in TP-Link is duplicating what is already in
config.toml.example, and given that we have recently added a lot of
new options I don't want to maintain multiple copies.
* Lots of anchor links were broken since we moved docs from README into
mdbook. Fix them all.
* Document that the key input feature is disabled since 0.4.0.
* Smaller cosmetic changes:
* Make TP-Link M7350 page consistent with TP-Link M7310 page.
* Fix indentation on some bullet points.
* Center-align the rayhunter logo in introduction.md to calm my soul.
It is still misaligned with the page title above itself.
* Add "edit on github" link in mdbook settings.
