merged changes from my repo Phing-Additions

change from me:

* make delete switch also run on a dry-run
It's very important to see what files would get deleted in a dry run, so this option is now also parsed if dryRun is supplied as true.

changes from andrewjshults:

* Makes rsync throw an exception on error rather than just logging
* Fixes bugs with the remoteshell param and adds documentation for the default options
added lost setter for rsyncPath + reformatting

* added the lost setter
* added property defaultOptions that can get overwritten with options
* reformatted code and docblocks a bit
