Log:
We have to add the no-cache header setting to adminview to avoid stupid bug in IE.. :(

When we use window.open to open a url, if the url already cached in browser tmp folder. The browser will use the cache first, even you set no-cache in html <meta> tag.

The only one way to solve this is:

1. Add a random parameter in url (let IR treat it as different url, or
2. Send the no-cache header through PHP header() function

I choose the 2nd way to solve this.

This could solve when user use pull-down menu to add template and the templates list does not change in blogsettings problem. 

* Actually, the data already changed in db and session but not in browser cache... so, we should use this way to force the cache expire. :(

** This problem never happened in Firefox ..
