Update the capitalization of HTTP 418 I'm a Teapot

[mvasilkov]

In rfc2324 (1998), the HTTP 418 message reads I'm a teapot, whereas in the latter rfc7168 (2014) it's spelled I'm a Teapot — note that capital T.

This is consistent with other canonical status messages, all of which have Every Word Capitalized.

The patch is here.

I'm amazed we were able to get away with breaking the spec like this for so long, considering how important 418 is :)

@mvasilkov Sounds like you've got all that is needed to open a PR. Feel free to go ahead.

@mvasilkov : You can also update 300 to Multiple Options from Multiple Choices as per latter.

Looks like teapot > Teapot needs to be updated in ASP.NET and Golang too 😛
