The config screen should allow to configure autopep8 options.

Add buttons for checking and unchecking all checkboxes.

Options:

• There could be separate buttons for each category
• There could be one button for both actions, flipping everything on and off. If the buttons are partially checked, start by checking them all

OR

• Instead of (big) buttons, maybe use labelled links in parens next to the group name like (check all - uncheck all)

How to stop loading the plugin if no autopep8 module is found ?

Similar to removing whitespace at end of lines on save.

Unchecked by default of course as it can potentially be dangerous.

Check for pep8 and autopep8 versions. They must be "compatible", and old autopep8 versions don't have the fix_string() function.

Preview can be interesting but it requires a new interface. Is it worth it ?
