Added call to show the prompt (the rating alert) explicitly

[amjaliks]

In some cases you may want to show the prompt for rating explicitly regardless Appirater settings.

Thanks for sharing but I think the rateApp method covers the majority of developer use cases.

More specific use case. :)

We wanted to add such logic in FearlessWheels:

• ask to rate, when a user is playing the game at least one day, and show a prompt only, when he or she wins the level ([Appirater appEnteredForeground:NO] and [Appirater userDidSignificantEvent:YES] do this job well);
• but we also want ask to rate, when a user wins the first series (world), regardless how long he or she is playing the game (an here comes my showPrompt in action).

In this case rateApp is inappropriate, because it immediately goes to a review screen, but we need only to show a prompt, so a user still has an option to decide, if he or she wants to rate the app.
