A few minor bugs

Thanks for a great module.

I just have a few minor bugs that I hoped to might be able to fix. Here goes:
1) the title of the block does not get itself value from the admin page.
Code should be this
$block['subject'] = variable_get('buddylist_list_block_title', t('My buddy list'));
Instead of:
$block['subject'] = t('My buddy list');

2) the block does not honor the "Number of friends to list in the user's friend block" on the admin page
the following for loop probably needs a break once if reaches the limit:
case 0 : // Shows buddylist block
if ($buddies = buddylist_get_buddies()) {
foreach ($buddies as $buddy) {

3) the buddylist more link disappears after the smileys are updated

4) the buddylist page should have the online status
