Log:
Merge Ahmad's code about dynamic plugin. Now developer can use:
$this->_isDynamic = true; or $this->setIsDynamic(true); to turn his plugin as a dynamic plugin.

And user can use :
{dynamic}
{$pluginObject->xxx()}
{/dynamic}
to play plugin in a cached page.

Only one problem is, it only pass the plugin object to the view, other obecjts like $blog, $url, ... will lost. So, if user/developer have to use those objects in a cached view, they should pass them to the cached view by them self. 

**This will increase the server loading and request time very much if too many plugins pass th cached view. So, use this function carefully.
