WebHost: Stats page adjustments

[duckboycool]

What is this fixing or adding?

A few different changes for things on the stats page on the website.

• Colors are assigned in the order of most played, since those are next to each other on the pie chart. Before similar colors often ended up next to each other by chance. I also replaced the palette generation with a method that makes neighboring colors far apart (since they're no longer kind of random on the chart) and which won't break asking for 360 or more colors.
• Capped the length of game names on the legend labels so that the legend doesn't take up as much horizontal space and cover things up as much. Although the legend (and also just kinda the line plot generally) are maybe of questionable value anyway with as many games as on the main website.
• Removed the legend on the per-game plots, since this seems to have been the intention from the comments. (Also was it intended that they're shown in ascending order of games instead of descending?)
• Made the width of the bars on per-game plots not tiny, so now you can see them better and actually hover over them.

How was this tested?

Looking at the page on local webhost, with some partially mocked data.

If this makes graphical changes, please attach screenshots.
