Create PDF Letter - support for single contact mode via URL

Some sites use 'Create PDF Letter' quite a bit and would like to add that as an available action in the Actions button.

Modify the PDF and PDFLetterCommon classes to fully support 'single' mode (when a cid is passed in the GET params).

The URL pattern for this is:

civicrm/contact/pdf?action=add&reset=1&cid=$contactId&selectedChild=activity

Here's an example of adding that action to the Actions button by customizing CRM/Activity/Form/ActivityLinks.tpl:

<ul>

{foreach from=$activityTypes key=k item=link}

<li class="crm-activity-type_{$k}"><a href="{$url}{$k}">

{if $k NEQ 3} {ts}Record {/ts}{/if}{$link}</a></li> {/foreach}
{* Adding button for Create PDF here. *}
<li class="crm-activity-pdf">
<a href="{crmURL p='civicrm/contact/pdf' q="action=add&reset=1&cid=`$contactId`&selectedChild=activity"}" title="{ts}

Create PDF Letter

{/ts}">{ts}Create PDF Letter{/ts}

</a>
</li>
</ul>

I think you could also add to the Actions button using the "links" hook, but I didn't try that out.
