FSX: Stata module to show names of files in compact form (Unix-friendly defaults)

fsx is a fork of fs. Both commands list the names of files in compact form. Note that files do not include folders or directories. The change in the fsx fork is that it suppresses hidden Unix files by default (much like the Stata command {help ls} or the Unix command of the same name). These files are revealed with the all option, similar to the ls -a syntax in Unix.
