Streamline the interface for category selection.
- If there is only one category at the top level, automatically pick it (both instcode and custom category cases).
- Text "Main Categories" eliminated in all but one case.
- Button text: "Change" replaced with "Pick main category", Pick subcategory, or "Show subcategories" as appropriate.
- "Select" option in select box eliminated when there is only one available option.
- "Javascript function: "check_selected" displays alert if "Pick subcategory" button was pushed but not subcategory had been selected.
