Ability to set the view controller tint

[markst]

TextView is using default window blue tint...

Fair point.

I think it should have class methods for setting that as well:

+ (UIColor *)tintColor;
+ (void)setTintColor:(UIColor *)tintColor;

Then, on - (void)setupStyles method, could do:

self.view.tintColor = [ESFeedbackViewController tintColor];
