This patch adds some missing newlines, trims some multiple redundant
final newlines into a single one, and trims few redundant leading
newlines.
According to POSIX, a line is a sequence of zero or more non-'<newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

This commit eliminates the possibility to add a conference AND a CfP in
one news. If you want to create both you will then have to create two
separate news. This makes it easier to get informations regarding CfP
and Conferences separate from one another
