Sort post categories in ascending order by default

[jeremy-jameson]

Suppose you create the following categories for a Subtext blog (in this order):

1. Personal
2. My System
3. SharePoint
4. Development
5. Infrastructure

When displaying the categories, it is preferable to list them in the following order:

1. Development
2. Infrastructure
3. My System
4. Personal
5. SharePoint

Add an "ORDER BY" clause to the subtext_GetCategory sproc to sort the list of categories alphabetically.
