Closed Issue #7, and modified iPad storyboard a little.
Changes:
	- Added ARMNewGamePromptViewController class
		- It presents a text field and allows editing of the text field, and enforces it’s length to be >= 3.
	- Added a Scene to the storyboard with a modal presentation of ARMNewGamePromptViewController
	- ARMPlayerInfo “isUserReayForLogin” was not functioning properly, so I fixed it.
