Request: restrict lava/water -> cobble creation when offline

[Clavus]

I'd like an option to disable contact between lava and water creating cobblestone inside faction territory, when nobody of that faction is online. It's a rather weird request, but this is my reason:

They're building mountains to get inside faction territory. Can't blame them from being inventive, but it sucks if this happens when nobody is there to defend his fort.

I think the code can be easily obtained by tweaking the source of this plugin a bit:

(instead of obsidian, turn it to air?)

Not currently planned, sorry.
