Refractor: Path Add utility unixify #478

Basically unixify all before workingm then transofom in function os os

Util: Add function sort_len that a list of string according to the lenght of its content
Fix: VimwikiRenameLink doesn't update links in diary #90
Test: VimwikiRenameLink with nested directories
Prettify comments in autoload/path + remove antipattern
Define osxify function helper to solve windows Vs Unix : see #478
Path: remove useless temporary fix convertion before calling relpath (redundant) : see #478
Test: Fix typo
Path corrected (Thanks to test)
