Jehan 08c3bb407b app: source tools should not be choosable for bucket fill stroke.
Since we can't select a source, the source tools would fail stroking
with an error. It was usable when stroking a path or selection as we
can have the source tool started while running these. Since only one
tool can be started at once, this is not possible when running bucket
fill tool (it would require some logics change on tools).

This change has 2 parts: add an "insensitive" column to
GimpContainerComboBox (allowing to mark some cells as insensitive), then
use this new attribute in the GimpBucketFillOptions to show all source
tools as insensitive.
