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

Fix #97

	- Also fix the corresponding translation when a problem arise.

	- 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.
