Graves more easily moddable via .xml

[ItchyFlea]

Could the hardcoded Grave definition be removed from the Corpse code so that custom graves can be created? Could you also extend the Grave code so that the filled grave texture can be provided via .xml instead of requiring a new grave class to be written?

I've actually got a task for this already, so yes it's intended to happen at some point.

Can that task be a mantis issue made available for modders to add any hardcoded stuff we find. You could use it to track these changes and gradually remove all hard coded dependencies throughout the code. Happy to raise an issue when I find one bit im guessing there is so few that 1 ticket can be used to track it no problem. Just a thought.
