Updated to make class ARC-compliant

I love the class you've created but wanted to update for ARC.

1. AppDelegate.m - removed - (void)dealloc and autorelease
2. ViewController.m - removed release calls for each listView
3. ECListView.h - updated attributes for *font, *textColor and *itemImage to (nonatomic, strong)
4. ECListView.m - updated attributes for *items to (nonatomic, strong), removed autorelease and retain calls

Any consideration you might give to pulling my request would be appreciated.
