[research] [draft] embed option in torrent description

[utkonostracker]

This is not a final issue, so if someone's interested in researching - please join me.

Currently sqtracker doesn't allow any embeds in torrent description.
This means you can't add preview in your torrent so user can't familiarize himself with content (watch trailer, listen a song from album and so on) before downloading.
This is overall acceptable but not much user friendly.

I guess it can be solved with additional field in torrent description (named "preview" or something like that) so sqtracker could generate embedded preview from it. This field may be customizable in config (if it's optional to fill, some categories may not require it, some categories may require more than one preview and so on).

Basic flow may be:
0 (pre requirement). System has predefined embed templates for most popular media sharing services.

1. User enters preview link in new field on torrent upload.
2. System checks the link to find domain (eq. youtube.com) and content id.
3. System finds embed template for this domain and fills it with proper content id.
4. System shows embedded youtube video on torrent description page.
   4a (alternative flow). If system was unable to find a corresponding template, it just shows preview link as an active hyperlink.

Most popular video services:

1. Youtube (easiest embed)
2. Vimeo
3. IMDB trailers

Most popular audio services:

1. Bandcamp (can have custom domains + no content id in url)
2. spotify
3. vk.com

Points to research:

1. Polish the flow
2. Finalize the list of video & audio services
3. Prepare the template for each service with macros instead of content ID

I think it's just as simple as adding an option for a picture or video
Most pt sites allow image descriptions, which is user friendly enough.
