Setup initial HTML code for the new blank page

[Cheery]

Hello. I've tried to find this kind of feature request without any success. So I think it will be very useful if the webmaster will be able to setup initial HTML code for the "blank" page created by the "new page" button. In this case all important parts, such as css file + special headers and footers, which correspond to the site design, will be inserted into the new file automatically.

Thank you.
