Added some UI customization

[claesjacobsson]

• Subtitle can be used in table.
• Font and text color can be set for header, footer, cells and detail view.
• Background color can be set for detail view.

Hi Claes, thanks a lot for the PR.

I must say, it looks really nice on your screenshots, but I’m not fond of putting that level of customization into the pod itself. I’ve discussed that in past PR, and my take is that the pod should be simple and straightforward, while keeping the door open to subclassing for advanced customization.

For instance, adding subtitle is a nice touch, but it won’t be useful in the vast majority of cases. On a more technical level, I think you should let the view loading code in loadView, not in the init (see documentation). Last remark, passing a large amount of parameters is always a bit tricky, but if you want to use dictionaries, I’d use one dictionary by label, and keep the UIKit keys for string configuration (à la NSAttributedString).

I hope that doesn’t sound too harsh, I really like seeing people building things on top of this pod. I just don’t think the pod itself needs this kind of addition (everyone always wants something a bit different, obviously). I’ll keep this PR open for a while, see if other people want to join the discussion.

Hey Vincent!

Your remarks are definitely valid. My PR was thrown together quite fast to
meet the needs I have in my current project. So I understand if you don't
want to merge the PR.

I will take a step back and see if I can contribute with some more generic
additions.

Thanks!
Claes
