Add $user_nicename to bp_core_get_userid_from_nicename filter

[megainfo]

For more compatibility, i suggest add $user_nicename to the filter

Actual Code of function bp_core_get_userid_from_nicename

function bp_core_get_userid_from_nicename( $user_nicename ) {
	global $wpdb;

	if ( empty( $user_nicename ) )
		return false;

	return apply_filters( 'bp_core_get_userid_from_nicename', $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM {$wpdb->users} WHERE user_nicename = %s", $user_nicename ) ) );
}

To,

function bp_core_get_userid_from_nicename( $user_nicename ) {
	global $wpdb;

	if ( empty( $user_nicename ) )
		return false;

	return apply_filters( 'bp_core_get_userid_from_nicename', $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM {$wpdb->users} WHERE user_nicename = %s", $user_nicename ) ), $user_nicename );
}

Easy, and valid, and this function also needs caching. :)

Putting into 1.8.
