TextTemplate should be an alias for NewTextTemplate

[Eric]

In the following script, the template engine does not recognize server variable:

tmpl = TextTemplate("""
{% for server in servers %}
   ${server}
{% end %}""")

stream = tmpl.generate(servers=['server.example.com',])
self.assertEquals(stream.render().strip(),
                  'server.example.com')

Use NewTextTemplate, TextTemplate is still an alias for OldTextTemplate at this point (Genshi 0.5 and 0.6).

However the doc says:

while TextTemplate is still an alias for the old language at this point, that will change in a future release. But also note that the old syntax may be dropped entirely in a future release. legacy text template syntax

There's no ticket yet for this AFAICT, so I'm retargeting this one to that end.
