hgweb: support alternate logo url
Clicking on the logo image/text in the hgweb interface brings the
user to the Mercurial project page. The majority of users expect that
this would bring them to the top level index. I have added a new template
variable named `logourl' which allows an administrator to change this
behavior. To stay compatible with existing behavior, `logourl' will
default to http://mercurial.selenic.com/. This change is very useful in
large installations where jumping to the index is common.
