OmniOutliner Transcribe WWDC Notes.applescript

(*
With a QuickTime file open, and an OmniOutliner file open that matches the title below, if this is invoked:

- If the QT file is playing, it is paused
  - If there is not a row starting with the right session number, one is created at the top level (with a link back to the QT file)
  - A new row is added with the current time code and the insertion point to the right of it and OmniOutliner is activated.
  
- Otherwise, playing in the QT file is resumed and QT is activated

- Setup:
	- Hook this up to a command key using FastScripts <https://red-sweater.com/fastscripts/> to make taking notes from WWDC session videos easier.
	- Open System Preferences, "Security & Privacy"
	- Select the "Privacy" tab
	- Select the "Accessiblity" entry in the left-hand list
	- Enable or add "FastScripts" to the list of applications (needed to press the right arrow key below).
