Rules change idea: regress opponent's pieces two levels instead of one

[simondorfman]

Change this effect from eruption:

Spaces with your opponent's pieces regress one level on the growth track (level 1 magma chambers become empty spaces).

...to this:

Spaces with your opponent's pieces regress two levels on the growth track (level 1 and level 2 magma chambers become empty spaces).

Why? It's very easy to block a path by playing a level 1 magma chamber. It very rarely happens that a level 1 chamber is wiped out by a volcano. This increases the chance of that happening. Maybe even this will not have much effect. Then maybe it would be worth trying a further increase to three levels like this:

Spaces with your opponent's pieces regress three levels on the growth track (level 1, level 2 and level 3 magma chambers become empty spaces).

Created two volcano.json settings for this: EruptOverflowEnemyTileAmount is the levels deducted from an enemy tile during an eruption, and EruptOverflowAllowCapture will determine whether excessive levels turn into empty tiles or whether they can wrap around into the opponents pieces. For instance, if you subtract 3 from 1 you can either clear the tile or get -2 which turns into a tile of the opponents color of value 2. Basically it's either a capture or a clear.
