    Libraries files synchronizer.
    Searches for newer files present in projects, replaces older files in library.
    Searches for older files present in projects, replaces with newer files from library.
    First parameter - projects root directory,
    second - libraries root directory,
    third - files patterns, separated by semicolon.
