Initial work on threaded task, with an implementation of Table Content view data loading:

 - Removal of AMIndeterminateProgressIndicatorCell, and addition of a custom fork of YRKSpinningProgressIndicator which fixes bugs, adds threaded drawing, and adds a determinate mode.
 - Addition of a task system within TableDocument, triggering display of a large central progress indicator and stopping the window from being interacted with in any way that would cause a query while the task is running.
 - Add threaded TableContent content fetching, including use of the new task system and determinate progress bar; make fixes to improve threading stability and interaction.
