[enhancement] graphs of amount of raids

[jagp8]

I think it would be very interestig to monitor the amount requests of help for each raid each certain ammount of time.

I've experienced that sometimes when I start a raid and ask for help I get almost not response, but if I start the raid in a different hour I get help much more easily. I suposse that is due to strike times, where people focus on one punching certains raids, and ignore others, and this others increase the help requests. That's why I think it would be interesting to know which raids are increasing the requests because they are getting no help so people can decide to start those raids some other time.

PS: The raid finder it's great itself and very helpful, thanks!

As you can probably tell by the lack of commit activity on the repo, I haven't worked on this project in a long time -- a lot of the code is pretty outdated at this point. Realistically, I don't think I would be able to add this anytime soon.

However, I've considered rewriting the site, and have also wanted to have stats like this available. I'll keep it in mind whenever the rewrite does happen, though!
