Make plantlike drawtype more fun

Adds several new ways that the plantlike drawtype mesh can be changed. This requires paramtype2 = "meshoptions" to be set in the node definition. The drawtype for these nodes should be "plantlike". These modifications are all done using param2. This field is now a complex bitfield that allows some or more of the combinations to be chosen, and the mesh draw code will choose the options based as neeeded for each plantlike node. bit layout: bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant mesh shape: 0 - ordinary plantlike plant ("x" shaped) 1 - ordinary plant, but rotated 45 degrees ("+" shaped) 2 - a plant with 3 faces ("*" shaped) 3 - a plant with 4 faces ("#" shaped) 4 - a plant with 4 faces ("#" shaped, leaning outwards) 5 through 7 are unused and reserved for future mesh shapes. bit 3 (0x8) causes the plant to be randomly offset in the x,z plane. The plant should fall within the 1x1x1 nodebox if regularly sized. bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause the plant mesh to fill out 1x1x1, and appear slightly larger. Texture makers will want to make their plant texture 23x16 pixels to have the best visual fit in 1x1x1 size. bit 5 (0x20) causes each face of the plant to have a slight negative Y offset in position, descending up to 0.125 downwards into the node below. Because this is per face, this causes the plant model to be less symmetric. bit 6 (0x40) through bit 7 (0x80) are unused and reserved for future use. !(https://youtu.be/qWuI664krsI)
