Add portsvar.sh schell script into Tools/scripts.

portsvar.sh
  - print out variable defined through bsd.port.mk

example:
   % portsvar.sh PORTSDIR OSVERSION
   PORTSDIR = /usr/ports
   OSVERSION = 600034
   % portsvar.sh -e "PORTS[^_]"
   PORTSDIR = /usr/ports
   PORTSSUPFILE = /usr/share/examples/cvsup/ports-supfile
   % portsvar.sh USE_RUBY=yes RUBY_VER RUBY_ARCH
   RUBY_VER = 1.8
   RUBY_ARCH = i386-freebsd6
   % portsvar.sh -w ruby RUBY_VER RUBY_ARCH
   RUBY_VER = 1.8
   RUBY_ARCH = i386-freebsd6
   % portsvar.sh -w kde -e KDE_
   KDE_MAINTAINER = will@FreeBSD.org
   KDE_ORIGVER = ${KDE_VERSION}
   KDE_PREFIX = ${LOCALBASE}
   KDE_VERSION = 3.5.0
   MASTER_SITE_KDE_kde = ${kmaster:S@%SUBDIR%/@@g}
   % portsvar.sh -a
   list all variables through bsd.port.mk
   % portsvar.sh -a -w kde
   list all variables through bsd.port.mk including kde

portsvar.sh is easy tool to check out the variables used in
/usr/ports/Mk/bsd.*.mk.
