The main change is the use of a high-performance multithreaded http server for the backend (cheroot wsgi server, instead of our old wsgiref.simple_server). This allows the use of ete to serve efficiently many users at the same time.

Some fixes:

• order of headers in aligned panels work the same and well in all browsers
• multiple headers will not overlap now (not even a little), and their underlines have the exact size (do not extend to infinity)
• faces zoom correctly in aligned panels
• t.render_sm() (render with smartview) draws the full tree expanded by default
• updated and fixed examples in the examples directory
• minor corrections in closest_leaf() and related functions

Some additions:

• SeqFace accepts marking some positions
• t.distance_matrix() (faster and supersedes t.cophenetic_matrix())
• examples of extending the server api
• net_relatedness_index() and nearest_taxon_index()
