	Added make_blank_search function to make sure search page is returned when query is
empty
	Added gform_tabindexer function to fix tab index issue when multiple forms are on a page
	Moved root_relative_urls, scaffolding_remove_img_dimensions,
scaffolding_filter_ptags_on_images into base-functions
Move function in base functions files
Added template items into include so they are uniform on all pages and can be updated in one
place for all templates
