[geeklog-devel] COM_applyFilter doesn't accept negative numbers

If you call COM_applyFilter($var, true) you run into a problem if $var
is negative. In that case COM_applyFiler will return 0.
It comes down to this:
if( $isnumeric )
// Note: PHP's is_numeric() accepts values like 4e4 as numeric
if( !is_numeric( $p ) || ( preg_match( '/^([0-9]+)$/', $p ) == 0 ))
$p = 0;
Notice the preg_match won't match negative numbers. This is easily
fixed, but I'm not quite sure why is_numeric by itself isn't
sufficient. Is there any problem if we allow numbers like 4e4 to be
I found this because it is breaking the ability to change comment
display modes in pollbooth.php.
P.S. Note that I have NOT checked in any fixes for this.
