Fixing folder bugs:

Browse Source 
-> Folders were not loading with ordering properly persisted
-> When an item was put in the trash directly from a folder
   it was trying to remove the item from the folder again, sometimes
   removing an extra item from the folder
-> Making sure the FolderIcon always shows the _last_ 4 items;
   this was not working when the launcher was being restarted
-> Fixed a tiny rotation bug in the FolderIcon
