These patches moves the LayoutHandler and StructureHandler classes from the 
apps package to their more closely related area and fo packages, respectively.  
(Similar to the current placement for MIFHandler and RTFHandler.)  Have 
compiled and tested successfully with simple.fo.

See http://marc.theaimsgroup.com/?l=fop-dev&m=105280427018620&w=2 for basis.  
Also, this change will also be helpful should we move to multiple layout 
handlers (by separating the apps package away from the layout code), which 
Victor & others were leaning towards over the past week.

To patch:

OtherChangesNeededDiff.txt patch contains all-non LH & SH changes needed.

StructLayoutHandlerDiff.txt patch contains LH & SH class changes needed.  (Done 
separately because these need to move to different directories in CVS)

1) Apply both patches in either order.  
2) Move newly patched LayoutHandler to area and StructureHandler to fo packages.
3) Then build the application.

Thanks,
Glen
