Title: Add .no-sublime-package file (fixes #9)

Tell Package Control to extract plugin files from .sublime-package to Packages

Apparently now fresh versions of Package Control for ST3 install plugins to Installed Packages as .sublime-package and way to force installation to Packages is to add .no-sublime-package file.
