[gtk+/open-with-dialog: 12/52] open-with: turn the show_all_applications boolean into an enum

[Cosimo Cecchi <cosimoc src gnome org>]

commit a4283d7bab867ae2e9ebfc64089dd92cdcedce25
Author: Cosimo Cecchi <cosimoc gnome org>

    open-with: turn the show_all_applications boolean into an enum
    
    We have three modes of showing applications now:
    - RECOMMENDED mode: shows only the recommended applications
    - ALL mode: shows all applications, uncategorized
    - HEADINGS: shows headings for recommended and other applications
      (default).
