Add icon to left or right of the cell.

[Tchelow]

This is a suggestion on how we could have a left or right icon along with the title of the cell.
Obviously, instead of using a public var icon: UIImage? we should add it to the dataSource and adapt it to handle not only an array of Strings but multiple objects.
Feel free to change and adapt it in order to conform with everything else and put it to good use. I'd finish it, but I'm running short on time.

This PR refers to the issue #29.

Hello @Tchelow,

It is indeed a good idea 👍
As you said, the icons should be included in the dataSource via an object instead of a String.
I will work on that when I have time.
I would make dataSource items objects that conform to StringLiteralConvertible, so it could be backward compatible.

struct DropDownChoice: StringLiteralConvertible {

   let text: String
   let icon: UIImage?

   // Basic init method and StringLiteralConvertible init

}

let dropDown = DropDown()

// dataSource is an Array of DropDownChoice's

// can be used like this
dropDown.dataSource = ["simple text", "with", "no icons"]
// or like this
dropDown.dataSource = [
   DropDownChoice(text: "text", icon: UIImage(named: "icon_1"), 
   DropDownChoice(text: "with", icon: UIImage(named: "icon_2"),
   DropDownChoice(text: "icons", icon: UIImage(named: "icon_3")
]

Hi Kevin,
It's a good idea to make it backward compatible.
If I have time before you do, I'll try to finish it, but schedule is not looking promising 😂

Hello @Tchelow,

Don't worry, if you don't have time I'll implement it, plus, I'm actually implementing #27 which is gonna change a lot the code (also for the dataSource) so it may be easier to wait for it to be done and then implement this feature :)

By the way, if you have a screenshot of your app using the DropDown, I'm curious! 😄

[Tchelow]

I sent you an email with the screenshot.
And I'll wait for #27 then. :)
