v1.30.1

-- Fix not being able to set multiple stims using Add Stims edit box in StimEditGUI. Problem was in StimClass method to add multiple stims.

-- When StimEditGUI is closed and there are unsaved changes, alert user with message box that there are unsaved changes and provide opportunity to save changes before exiting. Also by default have don't ask again checkbox checked. The default behavior when 'don't ask again' is n effect is to exit GUI without saving. In connection to this, added a) new config option to AppSettings "Stim Edit GUI Save Warnings" and b) new option to MenuBox, in addition to 'dontAskAgainOptions', we now simply have 'dontAskAgain' which only provides a single checkbox and the checkbox settings is saved in AppSettings.cfg "Stim Edit GUI Save Warnings".

-- Modify slightly the wording of the warning to user to that they will be modifying an acquisition file directly when saving changes.

-- Add progress bar when StimEditGUI is launched because StimEditGUI is slow to load.
