[Enhancement?] Send UA to website to get full context page instead of xpath

[264768502]

Is it possible to add UA config to get different page to one website
Sometimes, website will feed different page according UA.
It will become easy to get clean full context instead of find xpath, and it will be friendly for mobile phone rss user to read. And easily for user to config.

At the moment the plugin uses a function from tt-rss to get the content of the page. I'm not sure there is an option to manipulate this setting directly. Therefore one must implement all stuff on its own.

For a page fetching option I'm Currently Researching:
Phantomjs php Library - https://github.com/jonnnnyw/php-phantomjs
