extensions: Allow customization of filetypes

Browse Source 
Define the variable :let g:airline_filetype_overrides to allow for
specific customization how a specific filetype will be displayed.

For e.g. a German display, you can use: >

    :let g:airline_filetype_overrides = {'help': ['Hilfe', ':%f']}
<

This defines how section a and b will look like for a window with that
specific filetype.

Closes #1888
