"Understand spoken Thai" tag line

I have changed the Lingopolo tagline to "Understand spoken Thai":

New header: understand spoken Thai

This is simpler than the old tagline (which was "Learn Thai through listening-based learning"), and it also focuses more on the Lingopolo benefit that you learn to understand spoken Thai, rather than on the method, that it is through listening-based learning.

The old header was as follows:

Old header: Learn Thai through listening-based learning

Of course Lingopolo will teach you to understand spoken Thai through listening-based learning, but what you're really interested in is the understanding.
