show messages in GUI, not stdout

[GoogleCodeExporter]

Add a scrolled text region near the top of the GUI to display incoming 
messages. The message currently are going to stdout which is not often visible 
to a user. To the right of the scrolled text area should be a button to clear 
the list. The list should show a few messages, always scrolled to show the 
newest, older ones can be hidden but accessible by scrolling.

Pushed an update to implement this feature.  The message window is a dock, so 
you can drag it to the top of the window as you prefer.  The position should be 
remembered.  

Also added a bonus 'regex' entry, with uses the QStringList::filter() function 
to show only messages that match the regex.  Leave blank to see all messages.  

I just had another idea: with the regex feature, it might be nice to allow a 
user to create more messages windows.  That way they can set up panes for each 
device, for example.  Though I suppose some `tail -f @ | grep "device"` with 
some INDI message listener would probably be more flexible.
