parray improvements

For the need to write out the contents of an array to a file,
I had a look into $tcl_library/parray.tcl and found two (minor)
things:

1.) for finding the longest key, it traverses the *lsorted*
   list. Here, sorting is just a waste of cpu-cycles.
   (as opposed to sorting in the actual output-loop)

2.) I wonder, if it could be easily extended with a few options
   to puts the formatted text to a specified channel (rather than
   to hardcoded stdout), or evenmore: to just return the text.
