4chan gallery, slideshow, grid, expand images

This extension adds the following features to 4chan and 4channel threads:
- Image grid view
- Image gallery (with slideshow mode)
- Expand all images

The image grid view shows all images of a thread in a grid. Grid mode is perfect for viewing the images of a thread.

Gallery mode shows a single image in fullscreen. Gallery mode looks identical to opening the image in a new tab. Keyboard shortcuts can be used to navigate between images.

Expand all images expands all images in the thread, the same way clicking an image normally would do.

Settings are available to customize almost every aspect of this extension.
