Add setting to allow automatic figure number to be based on chapter number

Currently, when adding an image and providing a title it numbers a Figure as Figure 1. <Title>, Figure 2. <Title> etc, it be great if it would label the Figure based upon its chapter. Assuming you have two images in Chapter 2 and one image in Chapter 3, it would be Figure 2.1 <Title>, Figure 2.2 <Title>, Figure 3.1 <Title>, etc.
