Feature: Add some sort of reload helper

[auriium]

Simple - add a "reload helper" object that allows you to return a config value, and also be reloaded. When reloaded the config value returned will change. I may propose an object in a future PR.

I think what you are suggesting is a configuration instance whose data can be reloaded. I've considered this before, but never got around to implementing it.

Example sketch:

interface MyConfig {
  String someOption();
}

MyConfig config = readConfig();
assert config.someOption().equals("valueOne");
reloadConfig();
assert config.someOption().equals("valueTwo");

This will be easier to add in 2.0.0 since we will have a more standardized means of creating configuration instances with arbitrary behavior.
