XF 2.x Shoutbox - Product updates

This release fixes a bug where the smilies box has no style applied to it and cannot be toggled. I haven't noticed this issue because on the same page I was running my Chat add-on as well and it includes a XF .less template that is missing in the Shoutbox.

Added option to display smilie button for easy smilie access.
Added option to post shouts in a dedicated thread.
Added widget option to set shoutbox content height.

Added option to enable Shoutbox navigation tab to use it in a dedicated page.
Added option to add content to the Shoutbox header.

Added option to use reverse ordering where input box is at the bottom.

Added option to autolink/embed URLs and media sites.
Also, user mentions are now possible.

This release fixes a bug in Beta 7.

This version fixes a /prune bug in XF 2 BETA 6.
A new option to auto prune shoutbox every x hours has been added.

• Added "View" permission.
• When shoutbox is collapsed, no queries will be done.

Added option to toggle shoutbox visibility.
