This minor release contains the following changes:

This release contains a few usability improvements and bug fixes.
* Adds the autoShrink property to the label object, to allow its fontSize to shrink when its text wouldn't otherwise fit into its size.
* Adds the Run This Card toolbar button for easy access to test-running the current card.
* Some overdue code cleanup, and a few bug fixes.

This release is focused on UX improvements and cleanup, and cross-platform consistency.

- This version adds support in the mac build for CardStock's .cds files to be associated with the Designer and Viewer apps, for easier opening of stack files.

- Merges GotoCardIndex into GotoCard(), which can now take a card object, a name string, or a card number.
- Changes from exposing card.index (first card is 0), to card.number (first card is 1) to better match the numbering shown in the designer.
- More big performance improvements, and many bug fixes.
