Add new ContentParamType2 "CPT2_DEGROTATE"

Browse Source 
This might break some mods, but it is important for all uses of the param2 to
be documented.

This doesn't need a serialisation version or network protocol version change,
as old clients will still work on new servers, and it is bearable to have
new clients getting non rotated plants on old servers.

^ The rotation of this node is stored in param2. Plants are rotated this way.
Values range 0 - 179. The value stored in param2 is multiplied by two to
get the actual rotation of the node.
