Use a simpler mechanism to create thumbnails. Still quite slow, though.
Cleanup the bitmap resource during thumbnail creation
Put thumbnails into a separate repository; they are also done asynchronously so not all are available when other data is present
Remove 'location' from 'locationplacename', 'locationcity', 'locationcountry'
The Searcher class now updates its reader when it receives notification that the index has been updated
A 'missing thumbnail' image is returned
Solve an issue of the thumbnail indexer stopping (due to closing the index from a background thread)
Add a more effective & searchable date field
Page controls on the bottom, finally
