[DGD] Updates to LXR site for DGD

[Kris Van Hees]

The following changes have been made to the LXR (cross reference) site for DGD
sources:

	- The freetext search link has been removed since there is no glimpse
	  search engine on the server anymore (for now).
	- The diff markup function works now (due to a Perl upgrade the diff
	  script was broken).

	Cheers,
	Kris

 - the Constitution to survive the first hit, and
 - the Dexterity to run fast enough to avoid being hit a second time.
