Renamed some TightDB references in the RLMDemo.

@jp: Please review, but I merge right away for the release.

Great changes, clearly. The only thing I don't like (in my original code) is

NSLog(@"%@ is %@", row[@"title"], [(NSNumber *)row[@"checked"] boolValue] ? @"checked" : @"unchecked");

Let's change that to a slightly more readable

BOOL checked = [(NSNumber *)row[@"checked"] boolValue];
NSLog(@"%@ is %@", row[@"title"], checked ? @"checked" : @"unchecked");

This would be prettier with a typed version of find: but that doesn't exist in the API yet :(.

Just to note, once we change the return type from RLMRow * to id you will be able to drop the cast to have BOOL checked = [row[@"checked"] boolValue];

For anonymous objects, or id, I still like being explicit and casting it.
