devbook.xsl: Indent with spaces only.

There were 265 lines with 8 initial spaces, and 136 lines with an
initial tab. Unify it to use spaces only. (This also agrees with
"tabs are not allowed" in the devbook guide.)

Add an Emacs local variables block for indent-tabs-mode.

Remove trailing whitespace in lines.
