[PATCH] Implement svn rm --keep-local

Hi,
Attached patch adds option "--keep-local" to svn rm command. With this
option files and directories will be removed only from repository, but
it will remain in *current* working copy. This means that path will be
removed in other working copies after performing update.

Implementation details
=================
Keeping files is very easy: just don't remove them if --keep-local
option is specified.

Handling directories a little bit harder, because they are removed
after commit. So I've implemented storing boolean flag keep_local in
"this_dir" entry. When Subversion is processing log_do_commited
command for deletion it looks for keep_local flag and remove only
administrative directory if keep_local is TRUE.

I have only one question: is format bump required in such situation? I
added only new field to entries file and special meaning for contents
of killme file. So if older client will use new working copy, it will
just ignore new entry field (keep_local) and ignore contents of killme
file.
Of course directory will be removed from disk after commit, but I
think it's not a problem.

I've not been writing Subversion code for several month so I'm posting
my patch here :)

Add option "--keep-local" to svn rm command to keep deleted path in
current working copy.

To keep files just don't remove them. For directories set keep_local
flag to TRUE on "this_dir" entry and use it in log_do_commited.
