Minor project management updates.

* Update .gitignore
* Add a SublimeText project file
* Add an Icon.png which is used by my git client.
New icon for Windows.

Windows now uses the same icon Mac does.
Make qmake play well with Mac builds

Includes .plist and .icns files automatically now.
Compiler warnings.
Make the textual reporter sort the leave.

Sometimes, the leave was printed in a partially unsorted
fashion.  I suspect this has to do with using opponents
with no racks.  Whatever the cause, sorting it is trivial.
