new: parameters module refactored. The API is more simple now, there is no need to provide a module name anymore, this last is automatically guessed. Also, a new 'label' field can be provide when declaring a new parameter. It will be used instead of the name. new: email parsing refactored. My first attempt was really ugly. I did not really studied the various RFC describing how messages are formatted or what IMAP fetch queries can do. Now, I hope this new code will face better unknown types. At least, It will be simpler to update.
