Add support for port statuses (types) reported by Univeral Videohub.

ChangeLog

  * Display where each input is being routed.
  * Add support for testing the program using pre-recorded commands
    in text file by using -T / --test-input option.
+ * Add support for port statuses (types) which are reported by
+   Universal Videohub.
 
 2014-11-28 : Version 0.3
  * Rename -v / --verbose parameter to -d / --debug.

   - Video output port names
   - Video output routing
   - Video output locking
+  - Input/Output port statuses
 
 The following features found in bigger Videohub models are currently
 not supported (I don't have the hardware):
 videohubctrl is controlled using command line parameters. Here is a list
 of supported command line parameters:
 
-videohubctrl Version: 0.3 Git: 0.3-dirty
-
- Usage: videohubctrl --host <host> [..commands..]
-
 Main options:
  -h --host <host>           | Set device host name.
  -p --port <port_number>    | Set device port (default: 9990).
