[izpack-devel] TreePacksPanel

[Vladimir Ralev]

Here is another screenshot, I added the pack sizes (turns red when a 
selection change has updated the sum of the child packs, this way it's 
easier to keep track on which packs affect other packs and how the size 
is distribuited among tree parents). Any suggestions?
