The directory diffing phase in the VersionVault client exists in order to

properly get change type and metadata for added, deleted, or renamed files. This

was hitting problems with added or deleted directories, adding them as

additional changed files. These would then get added to the diff with garbage

diff content and bad paths. This change updates the directory diffing to only

add things to the file list if they are actually files.

Set up a UCM activity with added, nested directories. Saw that the resulting

rbt diff output only included the changed files.
