Fairy ring refactor

Reimplemented the travel log, fixes the issue where all the travel log interface text collapses in on itself
Travel log now displays the relevant code
Log sorting implemented
Fairy ring now remembers the last entered code and automatically re-enters it when opened
Fairy ring no longer skips letters
Direction clicks in quick succession now turn the wheel multiple times
