[KPhotoAlbum] Bugfix-Suggestion Annotation Dialog

[Steffen Jost]

Hello,

with the attached patch, image descriptions are now preserved as the 
were entered by the user.

The current version of Kphotoalbum (from git) alters image descriptions: 
for example, any HTML-code is removed from the image description, if the 
image is opened a third time with the annotation dialog.

Note that my patch suggestion is different from the one suggested by the 
theBro on 04.02.2010, which had some unpleasant side-effects and which 
was not applied to the trunk.

I also checked that entering XML-tags in the description does not cause 
any problem (they are still escaped within the database, as before the 
patch).

The only drawback of my patch that I could determine is that copy&paste 
of richtext into the image description looses its formatting and links 
immediately - without the patch, the richtext formatting was only lost 
upon reopening the image in the annotation dialog. However, I argue that 
this is a rather odd behavior anyway: if one is allowed to paste 
richtext the first time, then it should also be preserved second time, 
especially if one does not touch the description input box at all.

WARNING: I have no experience with the development of Kphotoalbum, so 
please help me and please tell me whether my suggestion is welcome or 
not. While I have some professional training as a programmer, I have not 
much knowledge about about C++ nor Qt. Luckily, the suggested fix is 
very simple.


Cheers,
  Steffen.
