Patch Set 1:

With the change
http://egit.eclipse.org/r/#change,745
we are fetching always the latest jars available on
http://download.eclipse.org/tools/mylyn/update/weekly/e3.4
currently we get there
org.eclipse.mylyn.wikitext.core-1.3.0.I20100521-1600-e3x.jar
and
org.eclipse.mylyn.wikitext.mediawiki.core-1.3.0.I20100521-1600-e3x.jar

If we need newer jars I need the URL of the corresponding p2 repository.
