[dev] Kronolith patches for Categories and Permissions

[Jason Rust]

This first patch is so that Category Management is not shown to a guest
user which would allow them to add category entries to the database:

< $prefGroups['category_management'] = array(
<     'column'  => _("Other Options"),
<     'label'   => _("Category Management"),
<     'desc'    => _("Add, remove, and edit categories."),
<     'members' => array('category_management'));

> if (Auth::getAuth()) {
>     $prefGroups['category_management'] = array(
>         'column'  => _("Other Options"),
>         'label'   => _("Category Management"),
>         'desc'    => _("Add, remove, and edit categories."),
>         'members' => array('category_management'));
> }

This second patch fixes the javascript for creating the permissions
button that shows up next to the Calendar Type.  There was never a type
2 in any version of the CVS so it looks to be a holdover from the
initial commit of the code.  So this patch makes it so a button with Permissions
shows up next to shared calendars, but no button shows up next to private
calendars.

<             document.shares.accesslist.style.visibility = 'visible';
<         } else if (type == 2) {
<             document.shares.accesslist.value = '<?php echo _("Permission") ?>';
---
>             document.shares.accesslist.value = '<?php echo _("Permissions") ?>';
