Subject: [PATCH] - in Excellon Editor fixed the selection issue which in a
 certain step created a failure in the Copy and Move tools. - in Excellon
 Editor fixed the selection with key modifier pressed - edited the mouse
 cursors and saved them without included thumbnail in a bid to remove some CRC
 warnings made by libpng
