Title: Added Textfield class

I added a full ```PretzelTextfield``` class! Well, not full, but it has all the basic functionality of editing strings and saving / loading them correctly, in a similar way to the textfield in Params.

This is what's not implemented yet (also listed in _Textfield.h_):
- make textfield clip and scroll text
- accept int and float variables
- allow to move cursor position with mouse or arrow keys
- allow copypaste
- lose focus after not editing for a while?
- fire signals on start and end editing, like iOS

I also updated the example to show how to use it.
