Second pass at refactoring and removing obsolete code from post editor

git-svn-id: http://ios.svn.wordpress.org/trunk@4031 7d847f7c-ffe1-4a24-85be-b788d016d96a
Removed unused statuses form EditPost

They are in post settings now

Final pass at edit post cleanup:

* Use automatic nib detection (with ~iphone and ~ipad suffixes)
* Removed redundant isTextViewEditing
* Remove pre-iOS5 checks
* More unused code removed

Instance variables still need to be renamed to follow naming
conventions, and some IBOutlets are still defined as properties, but
there should be no unused or redundant code by now
