[Request] make timezone for achievements more prominent about octoprint

[foosel]

I've done this:

• timezone information, "time based" indicator and link to configuration in achievements overview
  
• ability to reset time based or all achievements from the settings
  
• offer to reset all time based achievements on change of the configured timezone
  

Using the client side timezone wouldn't work - there might not be a client connected at the time the achievement is unlocked, so I have to rely on the server time. I tried squeezing a link to the config into time based achievement unlock notifications, but everything I tried to achieve that just looked horrible.

Will be in 1.10.1

The screenshots look great, I like that combination of solutions. The option to reset all from the settings page is good touch as well, not everyone would think to try clearing the plug-in data on a different part of the ui if they did want to reset all for whatever reason.

🎉 looking forward to the update!
