hgweb: fix help pages title in gitweb and monoblue
Help pages in gitweb and monoblue were setting a completely inappropriate
title: "Branches". Let's have a proper title (copy-pasted from paper style).
{header}
<title>Help: {topic}</title>
<link rel="alternate" type="application/atom+xml"
href="{url|urlescape}atom-tags" title="Atom feed for {repo|escape}"/>
<link rel="alternate" type="application/rss+xml"
href="{url|urlescape}rss-tags" title="RSS feed for {repo|escape}"/>
</head>
<body>
<div class="page_header">
<a href="{logourl}" title="Mercurial" style="float: right;">Mercurial</a>
<a href="/">Mercurial</a> {pathdef%breadcrumb} / help
</div>
<div class="page_nav">
<a href="{url|urlescape}summary{sessionvars%urlparameter}">summary</a> |
