* improves previous commit 3b5cbef652
and previous 3d_armor commit d7ae85b7f6 ,
the problem is that both server and client must be equal protocol, so
this ugly hack check if this was loaded into FinalMinetest or Multicraft
to dinamically check client nature and re-registering the model when
server and client do not have same player models due the colisionbox check
* NOTE: the check already need to check if the engine is old and the server not,
so the conditional just try to do exact check agains TRUE boolean.
* Closed https://codeberg.org/minenux/minetest-game-minetest/issues/12
fixed the problem of collisionbox for the lufix player in ugly way but
much more effectivelly due can be mixed in FinalMinetest and Multicraft
* fix model preview based on client view, not on server engine version
for the skindb mod
