More flight cancellation options

[AfkF24]

Idea

Add config options to set whether /f fly should only be disabled when in combat with players, mobs, both, or completely disabled (let combat logger plugins handle it). As of now, it gets disabled whenever you damage something (even when punching item frames).

Details

Basically:

commands {
    fly {
        disableOnCombat {
            enable=[true|false] #should the module be enabled at all
            players=[true|false] #if module is enabled, should fly get disabled vs players
            mobs=[true|false] #if module is enabled, should fly get disabled vs mobs
        }
    }
}
