Zero additions option

[GoogleCodeExporter]

Add new option to zero destination blocks instead of adding destination data. 
Produced patch will be extremely small because it will contain copy operations 
only.

This option is suitable when destination file can be synchronized with the use 
of faster or more effective way than applying patch, e.g. with some kind of 
cluster download.

Added supporting options -zb <bytes> and -zr <percent> with reasonable defaults 
to provide as compact blocks as possible while keeping delta small. This helps 
effectively update files decoded from zeroed deltas with the use of bittorrent, 
rsync or similar protocol based on block hashes.
