Destroy the Core

[BennyDoesStuff]

Describe the feature you'd like
Add a new gamemode called Destroy the Core (DTC). There's often a hollow sphere (usually made of obsidian) with lava filled inside of it, and if the lava flows out a certain amount of blocks, the opposite team destroys that core. The team that destroys the core/all of the cores first wins the game.

Usefulness of the feature
This is a popular gamemode that is available in both PGM and Cardinal. Coding in this gamemode would put TGM more on par with these other plugins as it would support just about all the major gamemodes that those plugins support.

Additional context
Extremely similar to DTM, except you aren't breaking a block, you're trying to get lava to flow out of a certain place.
