Typo correction
Added various assets and UIImage category

Added champion, item, profile, and summoner spell icons to the Images
folder. Also added a UIImage category to allow scaling of images to a
specific size.
Match history work in progress
Table view cells no longer are obscured

Tab bar and status bar no longer obscure table view content. The fix was
made by replacing the UITableViewController with a UITableView embedded
in a view controlled by a UIViewController.
Merge branch 'dennis' into chris

Conflicts:
	LemonNotes.xcodeproj/project.pbxproj
Merge fix

Manual merge of 'dennis' branch into 'chris'.
Moving assets around
Added champion mapping fetching to data manager

RiotDataManager now fetches champion data and stores a dictionary
containing id to info mappings. Fix to allow Constants.h to be included
more than once (by static inlining the apiURL function). Match history
tab now shows champion icons.

Code cleanup and doc writeup coming soon(tm)!
