New preference to allow users to disable keyboard shortcuts.
Make Cookies.js an optional dependency. If not present, uses localStorage for user preferences.
Add support for a fixed location for sign videos defined by data-sign-div.
Add support for an audio poster image defined by data-poster for the image URL and data-poster-alt for the alternative text.
Added new demo to view player in translation at https://ableplayer.github.io/ableplayer/demos/translations.html
Hide transcript and description preferences if not applicable to the current player.

Set border-box on chapter buttons to prevent overflow.
Removed border-radius on big player button.
Apply both background and background-color styles on big player button, to limit bleed from outside styles.
Set both color and background on VTS alerts.
Remove right margin on checkbox labels in draggable windows.
Use CSS transitions in place of JS animations.
New styles to support Audio Poster image positioning.

Added a timeout to resolve promise looking for YouTube captions if they don't load, so player doesn't fail on YouTube videos with no captions.
Remove setFullscreen(false) when rebuilding player, which prevented the fullscreen button from reacting to changes.
Improvements to draggable window positioning calculations.
Check button status before redrawing controls to prevent unnecessary repaints
Fix broken internal timestamp tags due to sanitization.

Add new translation method this.translate( 'key', 'Default %1 String', [ args ] ).
-- supports arguments so strings with arguments can be handled as a single string.
-- ensures that if translations don't load, the player will still render.
-- ensure that default strings are available in the code at the point of editing, for easier comprehension.
Added missing strings to translatable strings; mostly in the Transcript Sorter.

Update positioning of transcript or sign windows when a user goes full screen to ensure that they are still onscreen and visible.
Restore positioning of transcript or sign windows after existing full screen.
Remove fullscreen polyfill intended to support browser without support for the FullScreen API

Added a visible drag handle in draggle windows (Sign language and Transcript.)
Only the visible drag handle is a draggable surface, to prevent unexpected changes.
Removed duplicate screen reader text from player controls.

Removed references and code for helpDialog.
Remove Fullscreen polyfill
Miscellaneous removals of unused variables and arguments.
Reduced the jQuery dependency to jQuery Slim
