Change the order of the directories creation

just making the order in which the directories are created more coherent
with what the code is doing.

- Creating the 'lib' directory before the writing of a file in 'LIBRARY_PATH'
- Creating the 'bin' directory before the writing of a file in 'SCRIPT_PATH'

At the end of the day it doesn't matter so much, as usually, those
directories already exist.
