#11 Remove the need to press enter (in a path box)

[Gert Hulselmans]

Variables which you put in a text box seems only get read when you add text to them.

When you add text to text boxes (e.g.: path boxes), I only get set when you press Enter afterwards.

If you change for example the path in such a box and you click on "Execute", the textboxes aren't read again. This can give misleading results.

Added focusLost method to update the text without requiring enter.
