Add basic mcollectived daemon batch wrapper for windows.
Add windows_prefix method to MCollective::Util to get the mcollective directory on a windows install.
Add Windows defaults for most MCO files

This commit adds sane defaults for the following files needed by MCollective:
server.cfg, client.cfg, classes.txt, mcollective.log, and rpc-help.erb. As
these are only defaults, any of these files specified by command-line options
or configfile settings will take precedence.
