Some update, see comment for full description

[ghost]

Added:

• package SyncedSideBar that will scroll to file in sidebar when you change tabs
• package SyncedSidebarBg that will apply editor theme for sidebar too, not only for editor

Settings:

• save_on_focus_lost will save document after you switched to other window, so you never need to press cmd+s
• soda_folder_icons will show folder icons from Soda theme, nice icons with retina support

@vladimirbazhanov could you please update pull?

I'm not sure about save_on_focus_lost. This should be optional probably.
