#684 Add support for watching system variables ($@, $!) in debugger perspective

[Kalle Richter]

Currently if system variables are set (e.g. $@ by GetOptions of Getopt::Long), they don't appear in the variables view. Consider the following code example:

use Getopt::Long;
my $verbose = 'Print verbose informtion';   # option variable with default value (false)
my $debug = 'Print debug information (implies verbose)';    # option variable with default value (false)
if (! GetOptions ('verbose' => \$verbose, 'debug' => \$debug)) {
    die('Option parsing failed due to error "$@"');
}

If you break at the die line, you can't see what's in $@ which would be useful.
