EntryIf lacks has_comments and has_pings

[jcdubacq]

EntryIf? has support for pings_active (timeout is not elapsed for the current post) and show_pings (there are pings/trackbacks or timeout has not elapsed for the current post). But there is no simple way to get a EntryIf? for just "there are pings".

The same holds for comments. This makes theme with comments detached from the comment form difficult to do. For example, I would like to use:

<tpl:EntryIf operator="||" has_comments="1" has_pings="1" has_attachment="1">

The simple fix is to add these to inc/public/class.dc.template.php (patch included, may need reformating). The old definitions can be left alone, even if show_pings can now be expressed as:

<tpl:EntryIf operator="||" has_pings="1" pings_active="1">

This can also be achieved by plugin, but plugins that redefine core functions of class.dc.template.php are bothersome.
