The practice session

Enhances thesession.org with tools to organise the tunes you're learning

- Adds a 'Practice' item to the menu - Removes pagination from the sets page - For each set adds 'nailed it!' and 'needs work' to rate how well you last played the tune - Also has a 'pin to top' button for sets you particularly want to focus on - All the above buttons are added to each individual set's page too - Sets are ordered based on when and how well they were last played
