Improved read-only script editing

[radpopl]

I have a request regarding the behavior when editing a read-only AVS script.

VDub currently throws a write error but refreshes the script.
Could it be that in this situation, VDub would display a dialog box: "Save script to read-only file": "Yes" or "Cancel"? If "Yes" is selected, it would remove the "read-only" attribute, save the file's contents, and optionally set the "read-only" attribute again? If "Cancel" just do nothing.

This is long abandoned, take a look at this fork:
