- Also added possibility for the poll's maker to edit this hidden results option.

	- Also added Framadate\Message à link attribute
	- Added local anchor #edit with vote edition
	- For now, when the poll owner check the new edit option (ie: "Votes are editable solely by their owner"), users get their update link on vote creation

	- Changed the smarty modifier poll_url to a function and added the vote_id parameter
	- Modified accordingly all poll_url occurence in templates
	- Added htaccess.txt to be sure to keep poll's URL changes up to date
	- Escaped some templates output in order to avoid to broke HTML
	- Using vote's uniqId instead of vote's id when it's needed

	- The goal here is to prevent the losing of the choices by having a bad name.
	- This is a POC, there is probably some cleaning before merge
