BF: fix issue with wx3.0 on OSX to do with fonts having odd names

For some reason 'Lucida Grande' is being called '.Lucida Grande UI'
and then spits an error

Now creating a pair of fonts at app init and using those throughout,
rather than using GetFont().SetFaceName() so often

On OS X there are lots of warning about improving performance by
using PostScript font names but apparently this is fixed in wx upstream

ENH: Fix compatibility with wxPython 2.8

Starting the Builder with wyPython 2.8 raised AttributeErrors because
Font's Larger() method is not available before 2.9.1. The application

was fixed by adding a check if Larger() is available. Using a smaller
font still seems to work and allows using PsychoPy on older wxPython.
