Add //replacebiome

[Spearkiller]

The Problem

Currently, there is only a //setbiome command. This makes it incredibly fiddly to change biomes and getting it to look right - often resulting in sharp lines between each biome, unless one takes a certain level of care to match the set position to the biome boundary.

Vanilla minecraft has the /fillbiome command which does a similar thing, and just like with the normal /fill syntax, supports an additional replace argument, allowing you to essentially whitelist the biomes to be changed. The issue is that much like the normal fill command, there is a limit to the size of the selection area.

Both of these fill different niches, but the opportunity is there for both to be met in the middle.

A Solution

A //replacebiome command that allows replacing only certain biomes with another biome for the given selection area, with a much larger selection area and ease of use compared to the vanilla /fillbiome command.

You can set a //gmask $forest for example in order to replace specific biomes. Given that we've had a request for this twice, it might be worth exposing as a dedicated command, but we would probably still give it a mask for targeting rather than specifically tying it to biomes.
