Icons for self modules
When I create my self module for ispconfig3, i must the image for this module load to the core images under /usr/local/ispconfig/interface/web/themes/default/.... Then I do an update of ispconfig3 and the image is erase from this order. I think a solution is copy the tempalte and rename than do ispconfig3 update not erase the images, but It's not the perfekt Way.
