Title: Allow `Pry.config.editor` procs that take a `reloading` arg

This allow the user to implement an editor proc that only blocks the Pry process if Pry is going to reload code when it returns:

```ruby
Pry.config.editor = proc do |file, line, reloading|
"subl #{'--wait' if reloading} #{file}:#{line}"
end
```
