[patch] for rails projects using markaby and selenium to write tests in .rsel or .sel format.

[gugod]

I discovered that, because markaby override ActionView::Base::render_template to properly calls Template::render of its own, it fails to call the template handlers for .sel and .rsel templates.

I attached a simple patch that get rid of the render_template override, and yet make the interface of Template::render be compatible with others.

(please ignore all those white-space differences in the page)
