Bump version to 0.3.0-dev for first dev-builds.
Ender Furnace: Don't allow automation to extract items when outputting to EC.
Ender Furnace: Scale down some values so the progress bars don't derp in SMP.
Refactor some event handler and chunk timeout ticking etc stuff. WIP
More chunk loading refactoring. Now more or less complete.

Also seems to work in initial testing, but more testing is required still.
