Add package for newLISP programming language

This adds the newLISP (10.7.0) programming language. newLISP is a general-purpose, Lisp-like scripting language. Currently has readline and ffi support disabled. Things work correctly but adding support for these two things in eventually would be nice.

Tested sucessfully on Samsung Chromebook 3 (XE500C12-K01US).

+  def self.build
+    # This works but readline and ffi are disabled. When using the
+    #  standard ./configure it's looking in the wrong place for ffi.h
+    #  and readline isn't linked against libtermcap/ncurses.
+    #
+    # Looks like the readline issue is the system libreadline vs the
+    #  one shipped with bash.
+    #
+    # Ideally I'll figure out how to get it building properly as follows:
+    # system "./configure --prefix=/usr/local --enable-readline --enable-ffi"
+    system "./configure-alt --prefix=/usr/local"
+    system "make"
+    system "make", "check"
+  end

+  def self.install
+    system "make", "DESTDIR=#{CREW_DEST_DIR}", "install"
