Solved a bug that happens when reused cell preserve its display avatar image when download images setting is set to false
instead of displaying the anonymous contact picture.
Storing references of TweetFeedItemView views in a ViewHolder instead of using findViewById each time the cell is reused.
Merge pull request #354 from R4md4c/release

Use ViewHolder in TweetFeedItemView
Change tweet feed items to have name and handle on seperate lines.  Also have ability to show different variations (Name only, Handle only or both)
Change to DM feed items to match standard status' with Name & Handle showing.
Update version to beta 3 and add change log items
Merge branch 'Upstream_release' into Upstream_develop
