Version 0.6.1

Changelog for version 0.6.1:

• Added a new test case for level 49 (Sort), made some cells' colors deterministic to prevent non-deterministic solutions, and reset leaderboards and histograms.
• Added tick marks in histogram graphs.
• Adjusted tick marks and numbers for histograms where bins equal the max value (aligned with bin centers).
• Fixed positioning of 'best' and 'latest' lines in histograms.
• Added 'prev' stats for the histograms (previous run data).
• Rearranged metrics in solutions and histograms for consistency.
• Simulation restarts from test 1 after stopping on a different test.
