    Add vim modelines and missing emacs modelines
    
    Add vim modelines to the files which only had emacs modelines, and add
    modelines to src/gs-shell-search-provider.[ch] and lib/gs-ioprio.[ch]
    which didn't have any. This makes it much easier to not accidentally use
    spaces instead of tabs.
