Patch chm_http tool
    
    This adds three patches to `chm_http` which:
    * Correct the short option for `--port` to `-p` (from `-n`).
    * Bind to "127.0.0.1" by default, instead of "0.0.0.0".
    * Display a message (untranslated, sadly) indicating the URL of
      the runing server, unless the new `-q` / `--quiet` option is used.
    
    All patches have been submitted upstream:
    - [jedwing/CHMlib#10](https://github.com/jedwing/CHMLib/pull/10)
    - [jedwing/CHMlib#11](https://github.com/jedwing/CHMLib/pull/11)
    - [jedwing/CHMlib#12](https://github.com/jedwing/CHMLib/pull/12)
    
    But, since the last commit to that repo was in 2009, I thought I'd
    submit them here as well.
