v1.73

v1.73 changes:

- New:
  - Big Comma Mode: This will make commas stand out much more, and it also changes the way text is spaced out.
  - Middle-clicking the directory button now opens the selected folder.
  - Right click or middle-click the displayed image to open the image directory.
- Fixed:
  - The image index now correctly updates with changes from outside the app. (Adding/Removing images)
  - Text files now won't be created even when you select "No". A saveable text box still appears for images without text files.
  - Images without a text pair can now be properly displayed without errors.
  - The displayed text file is now refreshed when saving. This correctly displays changes made by cleanup.
  - `jpg_large` files are now renamed to .jpg before loading.
  - Unresponsive directory button.
