static pages removed from themes.

"static" pages used to reside inside each theme under
templates/static.

Since the content of these pages is not bound to a specific theme
and users will probably want to keep them even if they change the
theme, they have been moved to <root_dir>/static.
Populate static/ at "bucket3 init"

Populate static/ with default pages if they don't exist.
v0.14.0

A new way of handling static pages.

Static pages are not part of the theme templates any more,
they reside in <root_dir>/static/
