fix issue with unsorting functions
fix importing Queue for py3; use separate folder for py2 and py3 lib2to3 packages; added auto_pep8_replace command to avoid use 'edit' in sublime3; use config option for 'format_on_save' in ST3.
use 'auto_pep8_replace' command insead of view.replace()
import lim2to3 before pep8
use separate folders (packages_py2 and packages_py3) for lib2to3 depends of python/sublime versions
support ST3
