Smarty 3.1.13 proper install, template system complete overhaul.

Updates Smarty to Proper 3.1.13
Combined all installation files in www/install
Moved Pager.tpl from common to frontend and adjusted codes in www/pages accordingly. 
Renamed www/templates/ to www/themes/ and adjusted site code accordingly. 
Updated Basepages to use Smarty 3.1's settemplatedir array. 
Updated schema and admin page to remove '/' theme and set 'Default' as the default theme.

Template system is now recursive. If you want to make a theme you make a new folder in www/themes/  from there you only need to add the files that include the code you are changing. All other files that you are not changing will pull from the default theme if not found in yours. A more detailed explanation to come. 

This should for the most part allow for the previous themes that are online and found in the nn forums. (i kinda like the "simple" theme personally)
