[TASK] Fix TYPO3 6.1+ compat, remove dependencies to EXT:fed

I made all the fixes for TYPO3 6.1+ and completely removed the dependencies to EXT:fed
Where I could find a fitting ViewHelper in current EXT:vhs, I used that one, where I couldn't, I copied the ViewHelper to EXT:notify. Furthermore I copied needed services from EXT:fed to EXT:notify.
This isn't a comment on your work at all, but would you mind performing SQL escaping on $table in the render() method of this ViewHelper before this gets released? It's not until now that I see this might cause some security issues.
