hgweb: treat branch attribute `closed' as more important than `inactive'

In the branches page, branches that are closed and are merged into another
branch are displayed as `inactive'. This patch changes that behaviour to
show these branches as `closed'.

For me, the `closed' attribute is more important than the `inactive'
attribute.

Branches that are not closed, and are merged into other branches will still
be shown as `inactive'.

Branches that are closed, and are not merged into other branches will still
be shown as `closed'.
