selection

* plug-ins/script-fu/scripts/add-bevel.scm (script-fu-add-bevel):
Applied modified patch from Barak Itkin that when there is no
selection makes the bevel be performed on the whole layer instead
of the whole image (which was broken in the first place). It also
fixes some bugs with setting the selection when there is no
initial selection.
