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).
