Claudia: weird buttons on "add new" -window

[ghost]

When adding a new program, "Add New" -window has weird buttons: OK and Close. OK should close window and add program. "Close" should be "Cancel" and adding program without closing window should be done by double clicking program name. Current behaviour is unexpected.

The buttons are the way they are supposed to, it was just missing a checkbox.
I've added one saying "auto-close", that will auto-close the dialog when OK is pressed.
Unchecking that allows to add multiple apps at once.
