Non-AJAX modes added

Two modes without AJAX were added in order to evade issues due to
JavaScripts.

Since tab showed only a dokuwiki contents read by AJAX, JavaScripts
registered to onLoad didn't run on clicking tab.
{{tablink>page1,page2,..}}  shows a selected tab with page transition on
clicking.
{{tabembed>>page1,page2,...}} shows a selected tab, while all contents
of tabs are embedded in the page.
