restrict suggestion

hi,
i have a suggestion about the level restriction.
it would be great to choose my own level for the restriction.

For that i changed line 327 to
if ( $level >= $restrict ) {

and than changed the restrict shortcode to the min level what a char should have to show.
The default setting could be 1
