vcs-svn: Replace = Delete + Add

Simplify by reducing the "Node-action: replace" case to "Node-action:
add".  This way, the main part of handle_node() only has to deal with
"add" and "change" nodes.

Functional change: replacing a symlink or executable without setting
properties will reset the mode.
