[PATCH -perfbook 2/4] ebook: Print page counts on upper-right edge of page

[Akira Yokosawa <akiyks@gmail.com>]

Page counts at the header area are invisible due to the narrow
margin of 0.2in.

Use fancyhdr package and print page counts close to the top edge of
paper.  Print them in "Grey" color and scriptsize font so that they
won't distract readers too much.
