Puts 2 borders around the image. The outside border is a Gausian blur of the image itself, the inner border is a colour.

This script has 4 options:

1. Border colour, pick the colour of the inner border.
2. Border size, the width of the colour border.
3. Blur amount, the amount of blur applied to the border.
