Configurable Default Flags

[Studio0rbit]

Is your feature request related to a problem? Please describe.
Every time I create a new world with mv, I do the same set of commands:
/mvm set monsters false
/mvm set animals false
/gamerule dodaylightcycle false
/gamerule doweathercycle false

Describe the solution you'd like
A config file that provides the ability to set default flags for a world so I don't have to type out 5 commands every time I create a new world.

Describe alternatives you've considered
Commands to set default flags instead of a config file
