Cleanup tasks

[Alex Merry]

http://community.kde.org/Frameworks/Epics/KF5.0_Release_Preparation/KDE4_References
lists a bunch of kde4 references that should be cleaned up.  Any row
that contains things that aren't review requests is up for grabs
(including the ones that say "in progress").  Just put your email
address in the last column.

Also, reviewing the open requests would be helpful.

Also, there's a bunch of "KDE 5 TODOs" in various frameworks.  Do
something like

  for dir in *; do
    (cd $dir; echo ">>> $dir"; git grep -n 'KDE \?5' | cat);
  done

to see them.  Some of these are API changes that either have to be made
or rejected by the end of this week.
