Make COPY and DCOPY flags for RoboCopy configurable.

Note that they are not included in the example configuration files as
these settings can easily mess up everything and should only be adjusted
with great care.

The default settings are valid on Windows 7 and Server 2012 and were
successfully tested on those versions.

Fixes #11
