There is no reason to limit the caracters that can be used in the name.
Thus, removing the regex.

Fix #97

	- As it is now, description can't be in error state : we are waiting the markdown implementation to eventually change that.
	- Comments are now normaly formated (newlines are taken into account)
	- The title, description and comment regexes are now useless. Deleted.

	- 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
