Allow QuickDialogTableView to be instantiated from storyboard

This changeset allows you to use QuickDailogTableView inside complex view layout.

1) Drag UITableView into UIViewController using storyboard
2) Set size and position
3) Assign class name to QuickDailogTableView
4) Add the following to your custom QuickDialogController
```objc
- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        self.useStoryboard = YES;
    }
    return self;
}
```

It may be useful if you want QuickDialogTableView to take only part of the screen and control size and position via UI.
