String 32008 should read "settings.xml" and not "guisettings.xml"

[eyal0]

The error message displayed when settings.xml is not found is incorrect.

The error message says that it's guisettings.xml that is missing:

However, the code is looking for settings.xml:

https://github.com/phil65/script.toolbox/blob/master/resources/lib/Utils.py#L119

The fix is to change the error message to remove "gui" from it.
