Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Avoid face attribute warnings in themes
    
    * etc/themes/deeper-blue-theme.el (class):
    * etc/themes/leuven-dark-theme.el (class):
    * etc/themes/leuven-theme.el (class):
    * etc/themes/manoj-dark-theme.el (manoj-dark):
    * etc/themes/whiteboard-theme.el (class):
    Use `unspecified` instead of `nil` as attribute for :background and
    :foreground to silence HANDLE_INVALID_NIL_VALUE warning.
