new default for 'verbose'

Now, the default for verbose is `getOption("verbose", default = FALSE)`

And we use messages instead of warnings

And the Rcpp code uses `Rcpp::message()` instead of `Rprintf()`

+========================
+
+- Set `verbose = getOption("verbose", default = FALSE)` by default, and use messages instead of warnings. Thanks to @jpquast for suggesting this change in [pull request 263]. This should prevent unexpected warning messages in packages that depend on ggrepel.

 ### Verbose timing information
 
+By default, ggrepel will respect the global `verbose` option, so please check `getOption("verbose")` to see if this is set to TRUE or FALSE in your environment.
+We can set the global option with `options(verbose = TRUE)` or `options(verbose = FALSE)`.
+
+We can override the global value by using `geom_text_repel(verbose = TRUE)` or `geom_text_repel(verbose = FALSE)`.

 Use `verbose = TRUE` to see:
