Task #7593: autogen creates the protocol files now in the namespace XXX_Protocol. Modified the sources to look in these namespaces.

Jan David agreed it makes sense, although some software covered is not
currently maintained by the RO software team.
All replacements happen in comments, so this is safe. (viewed svn diff | grep ... by hand)
Command used:
LOFAR$ grep -r -l seg@astron.nl * | xargs sed -i -e 's/seg@astron.nl/softwaresupport@astron.nl/g'
