backport and tweak internal functions and document it

Browse Source 
* backported internal fucntions cos the narcisits tenplus1 dont
  property document the changes.. the commit 457eb1838cd1e694052298a42c84cd7b061d809d
  of main master upstream tag has bugs inside changes and undocumented
  changes too, this commit was named "code tweaks" only!
* also backported commit ed74f3c4c4d3f4c7e17127fa26ac4f0adbd2900d
  named "add :is_inside() function (thx cora for idea)" non credited
  in changes
* add global node_ok, effect and yaw_to_pos global deprecated functions for
  backguard compatibility
* add selft mob_class list of functions also is_inside, yaw_to_pos,
  set_velocity
