added new pagination library
old pagiantion templates are no longer needed
a new pagination template for next/prev links
this was never a real function
also not used anywhere now
got the key and touch gesture paging stuff working
setting props has_prev & has_next make the code a little cleaner
added a test/demo page for pagination widgets
better formatting
documentation for the pagination widget
doc cleanup
correctly fallback to using the registered var 'pagination' if no data is passed as an arg (the simple case).
it was using as variable that got factored out in the context-preserving fix
