    fpaste: add simple fpaste uploader
    
    Someone please take this over and make a nice paste uploader. We probably
    need to allow for configuring the target host, username, etc.
    
    All of this should be doable now that we have IdePreferencesAddin.
    
    Also, we should make a GtkSourceLanguage→fpaste language mapping.
