adding MVC to umawings.

Added the post view to the MVC.

Added three new folders, M-Model, V-View, C- Controller.
added post.php in each of them getting them to do to extract query and
and return it doing view just with the urls.

-  you can visit umawings/controller/post.php?action=show to see the
post. the query is included from model's directory and the view's
structure is given back to the controller's directory.
example url : http://localhost/umawings/controller/post.php?action=show
yes, will change the action and add an id to select the exact post.

WILL BE BACK TOMORROW !! :)
