v0.51 build 4 (Testing beta)

Another build for testing out new features for v0.51 - including:

• The Auto-Crafter bot (and some new fixes so that it can collect seeds from Greenhouses).

• Ability to queue up crafting items even when your inventory is full.

• Drop items by dragging them up off the inventory bar.

• Vehicle trailer physics improvements.

• New tooltip for explaining how to recharge and repair vehicles.

• Fixing bugs with items that aren't supposed to stack when crafted (oxygen tanks).

• Trying out a different .jar app wrapper for making native executables.

To try out this version, you need to right click on MewnBase in your Steam library -> Properties -> Betas tab and select the "testing" version.
