Add scrollbars to 'lot clist' in Lot viewer

[Geert Janssens]

Hi,

attached you will find a patch (created with 'cvs -q diff -u') to add 
scrollbars to the list of Lots in the lot viewer. Without these scrollbars, 
the lot viewer window stretches beyond the screen if the list of lots is too 
long.

Note that the patch mentions 3 files as changed, although I only modified 2. 
The third gets modified by the autogen proces. (I am using
./autogen.sh  --enable-opt-style-install --enable-doxygen --enable-debug 
--prefix=/opt/gnucash
by the way to configure)

Files modified by autogen.sh:
