Update SDWebImage

[GabeJacobs]

SDWebImage updated to 3.7.3 but UIActivityIndicator-for-SDWebImage requires specifically 3.7.0. Can you update the podspec please?

FYI: AFAIK, the SDWebImage framework has implemented activity indicator feature.

- (void)setShowActivityIndicatorView:(BOOL)show;

- (void)setIndicatorStyle:(UIActivityIndicatorViewStyle)style;
