Title: Adds interface for plugins to modify amount and consumption of fuel in powered minecart

Relevant ticket (not created by me) [here](https://bukkit.atlassian.net/browse/BUKKIT-1492).

Adds methods to get and set fuel contents (in ticks), change the push modifier (to start/stop the minecart moving) and disable/enable fuel consumption entirely for the minecart.
I'm submitting the corresponding Bukkit pull request immediately.
