Transitioning to NSUserDefaults for saved user data
Merge branch 'dennis' into chris

Conflicts:
	LemonNotes/Classes/TAPSignInViewController.m
Using NSUserDefaults to save user info

When the entered summoner name is deemed to be valid, it and the
corresponding ID number are saved to [NSUserDefaults
standardUserDefaults].

Entering a summoner name no longer clears the text field to make it
easier to fix typos.
CocoaPods setup
.gitignore update
Playing around, no real commits (ignore changes)
Some doc changes
Merge branch 'master' into dennis
Constants.h update & test file removal

Constants.h updated to include some of the Riot API call URLs.
NSURL objects using urls for Riot API calls should go through
these constants so that changing the URL in one place will
update the entire app, if Riot updates API version.

Removed RiotApiUtil class, need more time design first.
Since Utils folder was moved into Classes, removed the
one left outside as a result of merging business (I think).
