items: Add option to shave image borders
A workaround for badly exported images that contain some garbage
at the borders. The amount specifies how many pixels should be shaved
from all borders (i.e. amount of 2 results in 4x4 pixels loss).
Applicable for particular items or whole album (<general> section)
with the following syntax:
<shave amount="1" />
