#149 Number of chars

[Scelt]

Just like number of lines and number of words, there
should be number of chars. Of course stats should be
sortable by it too.

And why? Because chars are the most accurate way to
really find out who have talked most since words can
be written right and wrong (space between even there
shouldn't be) and lines don't tell very much since a
smiley isn't same that 70 chars long line.

This shouldn't be hard to implement. Just everytime
you count a line take the length also or if lazy, just
calculate lines * chars per line. I think you already
take char count to a variable to calculate that chars
per line.

Please, do this. A little work and a huge improvement.
Thanks in advance, guys!
