Moved UI/View related classes from `utils` to `widgets`.
Moved `ReaderVideoUtils` to reader package.

Created a `utils` folder that contains `ReaderVideoUtils` and `ReaderUtils`. A few of the methods in `ReaderUtils` needed to be declared public because of the move.
Moved `SimperiumUtils` to ui.notifications
Moved Media related classes to ui.media
Moved `ThemeUtils` to ui.themes
Moved utils.stats folder to root and renamed it `analytics`.
Deleted unused `CommentBadgeTextView`
Merged `ImageHelper` and `ImageUtils' to one file.

Fixes #1454
Moved `PostUploadService` to ui.posts
Moved `NotificationsDismissBroadcastReceiver` to ui.notifications.
Moved `StatUtils` to ui.stats

Moved `MessageBarUtils` to ui.reader.utils
Deleted unused `DrawableManager` and `IntHashMap`.
Renamed `StatUtils` to `StatsUtils`.

`Utils` renamed to `BlogUtils` and removed duplicate Display methods (like dpToPx)
