RIGHTBOOTH 3.8.3 RELEASED

- Implemented the 'Retake video' and 'Retake photo' feature.  This allows the users to re-record a video they are not happy with and to re-take a photo they are not happy with.
- Added an additional text box which prompts for users to enter their name on the Text Message input screen. 
- Added a 'Session Designer' button on the Main screen.
- Added help text for all buttons on the Main screen.
- The Setup Wizard will now reset the session screen back to its default layout.
- Added the underscore character '_' to the 'On Screen Keyboard'.
- The program now detects a screen resolution change and then prompts the user to alter or reset the session layout for the new screen size.

- Bug fix: When using the Setup Wizard, ensure the colour of all text labels in the session is the same as the Title text colour.
- Bug fix: Changing any button font property now correctly applies the property to all other buttons in the Session Designer.
- Bug fix: The 'Reset layout' function (in the Session Designer and elsewhere) now correctly resets everything on the session screen back to their default size and position.

Note: This version replaces v3.8.2 (previously released on 18th Feb)
