Refactored PostsListFragment. Removed old string arrays and replaced with a proper PostsListAdapter. Added a new 'PostsListPost' model for speedy loading and scrolling of the list. Tweaked layout of post row to use new font in WPTextView and moved date to the right side.
Restores list item selection functionality.
Add local flag to PostsListPost model, so we can distinguish local drafts in the list.
Merge branch 'develop' into feature/post-list-improvements

Fixed up WordPressDB.savePosts() to use MapUtils for safer retrieval of Map values..
Clear the posts list when changing blogs.
Don't load more posts if zero posts are returned for a blog, or if we've loaded them all.
Use a constant for the 'viewPages' extra.
Don't include uploaded local drafts when getting the posts for the Posts list.

1st pass at stats service - very incomplete
2nd pass at stats service - still very incomplete
 * Updated post list row layout (also renamed layout file).
 * Display local drafts, drafts and locally changed posts with an orange status label in the posts list.
 * Added support for 'Scheduled' post status to be displayed.
 * When loading more posts with infinite scroll, only load the amount requested from the end of the result array. (switching to wp.getPosts someday wouldn't require this)
 * Don't override locally changes posts when loading more, in case a user modified a post at the end of the list and the next call reaches the end of all posts on the blog.
