Change default template to use includes rather than $Me

[korthjp17]

This will allow for a bit more flexibility so you can spec the full namespace to the include.

We will keep the files in the Model section for now in case someone is still using the $Me in their templates.

Rather than use $Me, lets try this:

<% if $SlideType == Image %>
  <% include Dynamic\\FlexSlider\\Includes\\SlideImage_Image %>
<% else_if $SlideType == Video %>
  <% include Dynamic\\FlexSlider\\Includes\\SlideImage_Video %>
<% else_if $SlideType == Text %>
  <% include Dynamic\\FlexSlider\\Includes\\SlideImage_Text %>
<% end_if %>
