@thekorn what is your take on this issue. Since WAL stuff has been taken
out we still need your take on 2) so we can close this bug

Bug description:
The recently merged changes to use journal_mode=WAL and adding some columns to
event_view requires schema upgrades.
1) Setting WAL journalling *permanently* makes the DB unreadable with sqlite
3.6 which is still widely deployed. Notably if I boot back into Ubuntu Lucid
Lynx Zeitgeist will no longer work as lucid only ships sqlite 3.6.
2) Contrary to what is stated in the merge request for the event_view changes
the event_view VIEW is *not* regenerated on each startup. That is one of the
whole points of doing schema versioning. This change makes Zeitgeist trunk
unable to return any results if run on an older db. Strangely enough it doesn't
raise any errors...
Guys - if you are making low level changes to our DB structure like both of
these changes are, please make sure you understand all the ramifications before
merging.
