recognize Unix-style hidden files

[Dimitrie O. Paun]

I have hundreds of dot-files/directories in my home dir,
and they show up in the open dialog, etc. They get in the
way.

The semantics associated in Unix with files starting with
a . is that they are hidden, *exactly* like the hidden DOS
files. We should mark them as such.

We're lucky in that the DOS world does not use files that
only have extension, so we have no semantical conflict.

ChangeLog
  Mark files starting with a dot (.) as hidden.
