Add statistics of compilations

[gschwann]

Add statistics to the plugin:

• Time spend for compiling
  • today
  • yesterday
  • last week
  • on average at work days (when there was a at least 1 compilation)
• Time spend for compiling
  • per project
• Success ratio of builds
• Number of farts during compilation. You need 🎤 access and AI for it?. Maybe that one is optional.

I'll try to implement all, but last one 😛
