Clear int box on first click

[redransil]

In the UI, an integer field defaults to zero. When you click on it, the zero stays in the box. Then if you paste a value, the zero stays as the last digit of the number you entered.

Example: if you have "35" in the clipboard and click on the field then paste, the field will say "350" instead of "35"

It would be better if, the first time you click on an empty integer field, the field gets cleared and you can paste.
