str_to_sentence

Hi, could we please have a function that converts a string to sentence case. Some code below with my attempt at this..

str_to_sentence <- function(x) {
paste0(str_to_upper(str_sub(x, 1, 1)), str_to_lower(str_sub(x, 2)))
}

stringr relies on stringi for these functions, so you'd need to get it into stringi first.

Just found this in stringi @hadley
library(stringi)
stri_trans_totitle("a Test", opts_brkiter = stri_opts_brkiter(type = "sentence"))

I'd really like to have the functionality as well!

@batpigandme I'm working on this for Tidyverse Developer Day.

Thanks :)
