Summary of Changes

This PR updates both the site and the admin feed modules.

The original intent was just to remove the inline styles but it became clear that neither of these modules were fit for purpose.

• inline style replaced with html valid and accessible dir elements
• noopener noreferrer
• unused variables removed
• adopted consistent coding of the if statements as used in all other tmpl (thanks @hackware)
• kept the existing site module css classes (even though they dont exist in cassiopeia for b/c with 3pd templates)
• improve xss protection on admin module links
• add some basic styling on admin module
• remove overly complex and superflous rtl/ltr code

Testing Instructions

Create 3 newsfeed modules for both site and admin as below

1. set the direction to rtl and the url to https://www.aljazeera.net/aljazeerarss/a7c186be-1baa-4bd4-9d80-a84db769f779/73d0e1b4-532f-45ef-b135-bfdff8b8cab9
