0.3.1 (Hotfix)

Looks like some of my lazy programming caught up with me

Bugs that should now be fixed:

• The combos of scores without a replay file were ignored for the Max combo line in the text boxes
• Combos over 10,000 weren't recognized and caused further problems
• Unreasonable scores distorted the skillset evolution graph. Now scores with rating over 40 are filtered

Further additions:

• Renamed two plots to be more accurate
• Added "Number of unique files played" line to the text boxes
