prevent resource leaks, delete preview and settings because they have no parent.

Commit by welwarsky :: r1100136 digikam/trunk/extragear/graphics/digikam/libs/dimg/filters/bw/bwsepiasettings.cpp:

fix parent/child relations, based on my understanding
Layouts do not take ownership of the widgets they manage, those must be either explicitly deleted or or be child of another widget in the tree.
KTabWidget takes ownership of its tabs, those don't need a parent.

Commit by welwarsky :: r1100133 digikam/trunk/extragear/graphics/digikam/utilities/imageeditor/widgets/ (previewlist.cpp previewlist.h):

allow construction of PreviewList without a parent
PreviewThreadWrapper must not be a child of the PreviewLists parent, this causes crashes when the parent widget is destroyed before the PreviewLists destructor is called

Commit by welwarsky :: r1098586 digikam/trunk/extragear/graphics/digikam/imageplugins/coreplugin/autocorrectiontool.cpp:

Fix resource leak: make PreviewList a child of the AutoCorrectionTool instance instead of the ImagePlugin_core instance and explicitely delete it on destruction to free the stored autocorrection filters

For some reason the explicit delete is necessary, otherwise I get a crash on closing the application.

Commit by welwarsky :: r1098582 digikam/trunk/extragear/graphics/digikam/libs/dimg/filters/auto/ (10 files):

autocorrection filters don't need to deep-copy the reference image, let them share data with the original copy and make sure its treated const

Commit by welwarsky :: r1098578 digikam/trunk/extragear/graphics/digikam/utilities/imageeditor/editor/editortool.cpp:

when setting a new filter, be sure to delete the previous one

be more pedantic about const'ness

QList::length() is Qt 4.5 only.
QList::count() is equivalent and works for earlier versions
