hgweb: add a sendtemplate() helper function
This pattern is common. Let's make a helper function to reduce
boilerplate.
We store the "global" template on the requestcontext instance and
use it. The templater used by the helper function is the same
templater that's passed in as an argument to the @webcommand
functions. It needs to be this way because various commands are
accessing and mutating the defaults on the templater instance.
