[Sillies] Replace current bunnyhopping plugin with Mikusch' tf-bhop plugin

We briefly had this plugin on the servers before replacing it with the one we currently use due to a bug that has since been fixed.

Unlike the current plugin, which manually adds lost velocity to players upon landing, this one hooks into the games memory to effectively NOP-out the code responsible for preventing bunnyhopping, leading to significantly smoother jumps.

Sure, I'd be fine with trying this one again.

Did we ever go through with this?
If not, I can look into putting it on to the servers for testing at some point.
