The new player model is in minetest_game since 25 nov 2016,
3d_armor since 27 nov 2016
Dependency on 3d_armor was removed, as it is no longer needed
Note: the extra '.' characters in settingtypes.txt are needed to make
the help text display acceptably in the minetest settings tab. Without
them, minetest removes all leading whitespace, and makes the help text
look messy.
