Added escaping for install in config.tpl

In the installation process, string like the one below should be a valid application name (or DB password).
> Framadate c'est vraiment super ! "Datez" comme vous voulez \o/

    - Ajout d'un editeur de markdown

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.
