URGENT FIX: code would fail in Ruby 1.9.3 exception does not exist
message at the bottom for uncategorized was all mangled, fallback to the old way it used to behave
automatic groups should be bootstrapped
Fixing neglect to determine whether a user has the permission to create a topic on a category (besides being able to create a post) in ListController, TopicList, and TopicListSerializer causing the "Create Topic" button to appear even if a user cannot actually create a topic in that category but can reply to a topic therein.
Revert "Making automatic groups available in CategorySerializer#available_groups, which, e.g., makes automatic groups available in categories' permissions editing dialogs."

This reverts commit 44c193e8a16d0d60b86f4ed8dea7c00ae3bf5fbe.
Revert "Fixing a bug which allowed groups to be created having the same name as an automatic group, precipitating chaos, as well as neglect to determine whether a user has the permission to create a topic on a category (besides being able to create a post) in ListController, TopicList, and TopicListSerializer causing the "Create Topic" button to appear even if a user cannot actually create a topic in that category but can reply to a topic therein."

This reverts commit f2547bdb86abec19a02520ab37fffbf1d49c3083.
