Suppergerrie2's Drone Mod

- Added crop farm drone

    - Prepares the land around it by getting dirt from the chest and placing it.

    - Automatically places water and farmland

    - Plants seeds and breaks fully-grown crops.

        - Compatible with all of the vanilla seeds (but it won't farm melon and pumpkin correctly).

    - This is a very complex drone so please report any bugs you find!

- Changed tree farm drone algorithm

    - This change will mean your tree farm is possibly incompatible with the new version.

    - Instead of using world coordinates for the offset it offsets from the chest so you can better determine where the tree farm is going to be.

- Fixed hauler drones underestimating the work and claiming a whole stack for itself.

- Added storage upgrade

    - Every upgrade adds 1 slot to the hauler drone. (Every drone can have the upgrade)

- Added filter upgrade

    - Only items in the filter will be picked up by the hauler drone.

    - The tree farm drone and crop farm drone will only use the saplings/seeds that are on its filter

        - Crop farm drone will always get dirt from the chest to make its farm eventhough it is not on its filter.
