Add bundle filter for publishers etc

[enchained]

Feature Description

Recently Steam stopped displaying bundles in search results and removed the Include Bundles type filter which was immensely useful when browsing per publisher who does good deals on bundles.
This was probably caused by another recent change with bundles on Steam.
I tried using SteamDB for same purpose, but looks like currently there is no way to filter any page by bundle type, nor to filter the Bundles page by developer or publisher.

Could you please:

• Add Bundle type filter/mode for:
  • Publisher, Developer and Franchise pages
  • Global sales page
  • Events pages
• Add developer, publisher and franchise filters for the Bundles page
