Shorten/simplify doc TOC by removing redundant Roundup in titles. We already have a Roundup label at the top of the page. Remove the word Roundup from each item. Roundup Features -> Features etc. The titles for the pages keep the word Roundup since it will show up on the tab/browser window title etc.

#!/usr/bin/env python3
import sys
import roundup

from roundup.demo import main

sys.exit(main())
