Add ability to search by event or todo title in list of journal items

[0xedward]

I usually search for items in my calendar or todo app. However, I can't search for deleted items since they don't appear in those apps, so I thought it would be nice to have a way to search through items in the journal because that's the only place I can find those deleted items.

The android app doesn't seem to have a way to do this, so I currently have to use the web client and use the browser's search to find items in my journal.
