- Dialog: add optional third arg: dialog name (by default taken from the

Browse source 
dialog's <name> entry)
- FileSelctor: new class derived from Dialog. It clones the file-select
  dialog and reports chosen files/dirs via callback function.

# Open file select dialog (subclass of the Dialog class).

# SYNOPSIS: FileSelector.new(<callback> [, <oper> [, <dir> [, <file> [, <hidden>]]])
#
# callback ... callback function that gets return value as cmdarg().getValue()
# oper ... string that describes purpose (put on the "OK" button)
# dir ... starting dir ($FG_ROOT if unset)
# file ... pre-selected default file name
# hidden ... flag that decids whether UNIX dotfiles should be shown (1) or not (0)
#
# EXAMPLE:
#
# var report = func { print("file ", cmdarg().getValue(), " selected") }
# var selector = gui.FileSelector(report, "Save Flight", "/tmp", "flight.sav");
# selector.open(); # see the Dialog class for other methods
