Add commandline-option "--nolisten-network".
Document database changes.
Update default database and demo database.

Push file version to 4, make "People" category positionable.
Added the option to strip out EXIF comments.

As Tobias writes:
I have two digital cameras. Both automatically add EXIF comments to each
image, which is annoying to fix. My old Olympus C-470 adds "OLYMPUS
DIGITAL CAMERA         ", my newer Canon IXUS 220 HS even adds pure
whitespace.  Such EXIF comments can now be defined and stripped out
automatically when new images are read.

Additionally, ImageInfo::setDescription() now trims the description string.
Make exif commentsToStrip escaping simpler.
Fix compile error that snuck in in rev 968450a.
Highlight current index in Thumbnailview.

BUG: 254641
Use user-defined image folder for new DB.

Use the KGlobalSettings::picturesPath() instead of a hard-coded folder
name as suggestion when a new database is created.
Update ChangeLog.
Implement KIPI::Interface::hostSetting().
Added face detection to the annotation dialog using libkface. Recognition is still to do ;-)

Conflicts:
	AnnotationDialog/ImagePreview.cpp
Added scaling the image to the recommended size before face detection. Fixed disabling the face detection button for videos.
