namespace clash with built-in farming mod in 0.4.16

[mikyra]

Unfortunately the mod doesn't follow conventions placing its data and functions not in a table corresponding to the module name (aka farming_plus), but in the table farming.

Leading to a clash with the built-in farming mod shipped with 4.016.

Well, to be percise there is even two clashes.
One with the field farming.registered_plants that gets happily reset to {} by the farming_plus mod.
Not a big deal as the built-in farming mod never makes use of it.

Worse is the clash with the function farming.place_seed() as this one is really needed by the built-in farming mod, but happily gets overwritten by the version shipped with farming_plus.
As an effect neither wheat nor cotton will grow if farming_plus is used.

IMHO data and functions of the mod should really, really live in the namespace (aka table) farming_plus to A) fix the current issue B) prevent future problems like this one.

To verify the named function really is the culprit I ran a quick 'sed -i s/place_seed/FIXME_place_seed/g' over the lua files of the mod.
Wheat is growing again after that operation.
