added relative time converter for displaying stats on profiles
fixed rolling stat graphs, starting graphs at proper index of stats
html templates for header and footer
changed graph bg to white. removed y axis offset for small y ranges.
separated updating player's stats and plots so that a problem with a 
player's plots don't stop the rest of the players' stats from updating.
Added automatic daily backup.
Surrounded pAProfileScraper with try/except block so that a fetch
timeout or index error (from scraping the profile) in one player doesn't
kill the rest of the players' stats updates.
cleaned up user table, but still not really satisfied. html is hard.
Reduced font size of x tics.
Minor rewordings
