Initial commit for issue #333 "Modernize Comments UI with Conextual
ActionBar for moderation and multi-select".

TODO:
1. Restore selected ListView Positions from the bundle using a Parcel.
2. Pop the "Reply" dialog on the "Reply" action item selected.
Cleaned up multiple server calls which were redunant.
Added the use of the MessageBarUtils ... very awesome. I might add the ability to customize it a bit more for my needs but for now it is pretty slick!
Corrected some Async getActivity() issues (inside Async Callback functions)
Added the callbacks for the Async Delete Task to return a set of commentIds which could be used to determine which comments were deleted and which comments were not, in the case of a failure
To Squash
Corrected an error where trying to use the list view when it was not visable (the fragment + parent activity were heading out of a on paused / on stopped as the user had backed out of the activity). Corrected an error where a user could back out of the activity during a refreshComments Async call and could cause the Refresh animation to never stop animating
Corrected major issues with deleting comments from the WP database and models. We are good to go now on trashing and item and not seeing it show back upin the local WP database.
DO NOT TEST THIS COMMIT as I Implemented a better design of the SherlockListFragment code to easier to use. DO NOT TEST AGAINST this commit as there are bugs I will need to clean up for it to even work. This is just to show what I think is a better approach to code design. I will follow up with all the fixes (selection) in a while. Further I will be removing quite a few more methods and hooking up notification to the CommentsDetail fragment, on selection change.
Complete overhaul of the CommentListFragment which simplifies the code but actually uses the adapter model correctly as I noticed I was interacting with the backing data incorrectly. This allows for us to hook up a data set observer and simplify the code even more + react to changes of the data from other fragments/activities. Happy.
Corrected a bug when selecting a comment.
A bit of style clean up.
Fixes for some local database sync issues.
Fixes and inclusion of modifications done from other bug/feature commits
which did not merge well. The commit SHA hashes
(CommentsListFragment.java) for which I added said code to
CommentListFragment.java (prob. should not have renamed but this code
rework would have still have to have been done), and ApiHelper.java are as follows:
