Allow script to run even if open

[vksmjones]

Allow a script to run even if the script's window is open within Retrospect. Windows tend to get hidden behind other windows because of the way that Retrospect displays information and I found out this morning that if a script window is open, the scheduled script will not run. Who cares if the script is open? If changes have been made to script and the user hasn't pressed 'ok', then the script runs without the changes. Or add an 'apply' button in addition to the 'ok' and 'cancel' buttons so the user can apply changes made to the script as needed without closing the script window and Retrospect uses whatever information is saved if the script is scheduled to run while the script dialog is open.
