OBS Lua Scene Count Up Timer with Active Scene's Name 0.3

Added the ability to display a hidden note from a scene in the dock.

1. You will need to add a new text field to the dock with the count up timer -- you will select this new field in step 2, in the "Dock note text target". For this example, I am using one called "dock_note"
2. Two new fields have been added to the lua script configuration tab. You will need to specify a "scene note prefix": example "note_". You will also need to specify the text field in the dock where the information should be displayed. example "dock_note".
   
   
   
3. In those scenes where you want to display a note from a scene, you will need to add a new text field to the scene with a unique name. example: "note_1", "note_2", "note_about bob", ... using the prefix identified in the "Scene note prefix". If you move the new text field to the very bottom of the sources list, it will be hidden behind the other sources in the list.
   
   
   
   
   
   
4. When the scene is active in the 'program window, the script will :
   • look at all the text fields in the scene until it finds one with the prefix. (example "note_1)"
   • read the text in the field, and update the text field in the "Dock note text target"

Added the ability to also track scene changes in the Preview window.
