Add plugin system for web page URL's

[Petr Nejedly]

Next to feeds, it should also be possible to parse a HTML page (or any text document) to return a list of 'feed items'

Hi zip,

I would like to have a very simple interface:

• URL is configured via Serviio-Console (maybe with a new type)
• Server asks plugin if it supports the url
• Server passes URL to plugin and plugin returns Container with MediaItems (Video-Url, Title, ...)

So very powerful plugins can be made.

it should also support folders, so that we can make series/season hierarchy - although it will be difficult to limit number of returned items. The presentation layer will ignore the hierarchy for now and return is as a flat list.
