start on loading my contributions into the list

* flipped sort order so most recent on top
* 'refresh' button fetches last few uploads

Todo:
* thumbnails for my contribs
* don't try to upload already-uploaded ;)
* convert records to completed as we upload
* auto-refresh
* detail view for my contribs
separate localFile & thumbnailFile deletions
fetch thumbnails in background after refresh

fixed 'unique' thumbnail filenames to include a random number, not just seconds
Fetch only the first incomplete record when trying to upload
save file records as complete on completion!
clean up title format a bit
"Commons" -> "My Uploads"
fetch remote image thumbs when complete
Merge branch 'contris'
