+Two related changes:
+1. Updates nandwrite to not attempt to write past the partition boundary when the last block is bad  
+2. Adds an option to nanddump to skip empty pages
+This prevents a nanddump piped to nandwrite failing because the last block in a parition is bad, even when the tail of the data coming out is empty.
