Adding a tagging system.

[catsmells]

A tagging system is a near-requirement for an adult site system such as GOONCAVE. In a manner that contributes to effective SEO and user experience, a proper tagging system needs to be implemented in such a way that works with its window manager.

I propose it work in the following manner:

• User adds tags via pull request to the taglist file.
• [Likely via JSON] tags are associated with each video.
• In the search bar, a user can enter tags with specific syntax.
  • Searching a single tag will display all videos with that tag.
  • Searching tags separated by commas will display all videos with the tags specified.
  • Searching tags separated by commas, but with specific tags prefixed with a minus (-) will exclude all videos with the specified negative tags.
• Tags aren't user-added in real-time; they will be moderated.
