Feature Request: The ability to run a command(s) when players achieves stat numbers.

[Marotheit]

Hi there,

I think it would be a neat feature to run a command(s) when the player achieves a certain number in a stat. This could be a neat way to reward players! Optionally, it would be helpful to run commands when a player achieves multiple stats.

As an example: When the player breaks 100 Stone and 20 Iron Ore, run lp user %player_name% promote trusted and msg %player_name You mined 100 Stone and 20 Iron Ore! You were promoted to the trusted rank!
