Expose size settings in IconicsImageDrawable about android-iconics

[str4d]

Another reason for supporting this is that I have found that the relative sizes of the Material Design icons do not match the drawables, because they don't include any of the margins that the drawables do. So I find that even where I do want a 24dp ImageView, I often need to set the IconicsImageDrawable size to less than that to have a consistent sizing between icons.

There are methods to set the size of the drawable:

And also to define a padding for it:

Sorry, I just realized I had typos in my first comment. Fixed.

I already use IconicsDrawable.setSizeDp() to handle this (although good to know about the padding method), but as IconicsImageView is meant to reduce the verbosity of using IIcons, it would be nice to be able to set size (and maybe padding) there.

@str4d oh yes i totally missed the fact that you were talking about the view :D
