Some node.cpp/h work moved to path_manipulator.

Header variable bsplineWeight removed from all.
Simplification of code with less functions in path_manipulator.

To fix: tips stop working because is handled by two static functions and
couldent call to path_manipulator from here. Vinícius, any work arround? lines

gez: ¿Puedes probar si notas algun bug o problema? principalmente con 
la herramienta nodo, gracias.
