Reflect RP account status in site stats

[azurelunatic]

In reference to #2048 / #2049, show the number of roleplay accounts vs. the number of non-roleplay accounts in /stats.

Where should this breakdown happen?

Flat total of RP/Other?
Active accounts?
Gender? (if so, as a fifth gender category, or a header with the four categories underneath?)
Recently active accounts: should there be a fourth category?
New accounts: should there be a fourth category?
(Will sp*mmers take advantage of this? (The answer is always yes.))
Demographics: location?
Demographics: age?
(I don't necessarily think that client type is a helpful thing to break down this way.)

Is it worth noting in the stats that this flag was added as of [push date for #2049] and that older accounts therefore may not be reflected in the stats?

Let's hold off on having an open issue for this until we see what adoption/uptake is like.
