Line element added, plus a lot of good stuff.

This element is another milestone on the road to awesome new elements.
Besides, it was necessary to add this element if I wanted to implement
comment lines someday.

I also added some minor changes in the way mppdown handles newline
characters: they are now really expected, throwing an exception if
absent, and a newline character is now expected after every paragraph.
This newline character is then rendered back by the LaTeX generator,
hence following the proper LaTeX syntax regarding paragraphs.
