Moved example scripts from examples to examples/scripts directly

Cleaned up the examples directory by adding a scripts subdirectory.

This makes it a bit clearer which Python files are example cmd2 applications and which are example Python scripts for use with the pyscript command.

+This is a Python script intended to be used with the "python_scripting.py" cmd2 example application.
+
+To run it you should do the following:
+    ./python_scripting.py
+    pyscript scripts/conditional.py directory_path
+
+Note: The "cmd" function is defined within the cmd2 embedded Python environment and in there "self" is your cmd2
+application instance.
