Add fileschanged, a client to the FAM (File Alteration Monitor) server.

Here's how the fileschanged FAM client works: you give it some filenames
on the command line and then it monitors those files for changes. When it
discovers that a file has changed (or has been altered), it displays
the filename on the standard-output.
