--splitby=none is the new default, allowing all blueprint phases to be
written to a single file. old behavior of one phase per file is
supported via --splitby=phase.
- make depth and name parameters optional
- allow depth to be negative to indicate top-down instead of the
previous hard-coded bottom-up
- add --cursor for specifying start position (game cursor is not needed
if this param is specified)
