Title: Added more complete tmerc to cartopy translation

This PR takes advantage of recent changes to cartopy (SciTools/cartopy#309) to allow more varied data with a TransverseMercator coord system to be plotted using Iris. It does this by adding more complete ```as_cartopy_crs()``` and ```as_cartopy_proj()``` methods for the ```TransverseMercator``` coord system.
