hgweb: rename the main attribute of instabilities
Let's make "instabilities" list contain items with "instability" key as opposed
to "name" key. This way it's more explicit and more consistent with the log
command-line template.
<table class="logEntry parity{parity}">
<tr>
<th class="label"><span class="age">{date|rfc822date}</span>:</th>
<th class="firstline">{desc|strip|firstline|escape|nonempty}</th>
</tr>
<tr>
<th class="revision">changeset {rev}:</th>
<td class="node"><a href="{url|urlescape}rev/{node|short}{sessionvars%urlparameter}">{node|short}</a></td>
</tr>
{parent%changelogparent}
{child%changelogchild}
{changelogtag}
<tr>
<th class="author">author:</th>
<td class="author">{author|obfuscate}</td>
</tr>
<tr>
<th class="date">date:</th>
<td class="date">{date|rfc822date}</td>
</tr>
{ifeq(phase, 'public', '', '<tr>
<th class="phase">phase:</th>
<td class="phase">{phase|escape}</td>
</tr>')}
{if(obsolete, '<tr>
<th class="obsolete">obsolete:</th>
<td class="obsolete">yes</td>
</tr>')}
{ifeq(count(instabilities), '0', '', '<tr>
<th class="instabilities">instabilities:</th>
<td class="instabilities">{instabilities%"{instability} "|escape}</td>
</tr>')}
<tr>
<th class="files"><a href="{url|urlescape}file/{node|short}{sessionvars%urlparameter}">files</a>:</th>
<td class="files">{files}</td>
</tr>
