Add "Create PCP" option to Joomla Menu Manager

Admins need a way to create a front-end menu item for "Create a Personal Campaign Page" - using the new mechanism (as we now have for Online Contribution Pages, Event Info and Register, etc.).

The view "title" s/b "Create Personal Campaign Pages".

The URL is: civicrm/contribute/campaign
Params are: action=add&reset=1&pageId=$contributionPageId

In the new default.xml for this, I think the main param line is:

<param name="id" type="sql" default="10" label="Create Personal Campaign Page for" query="SELECT cp.id, cp.title FROM civicrm_contribution_page cp, civicrm_pcp_block pcp WHERE cp.is_active =1 AND pcp.is_active =1 AND pcp.entity_id = cp.id AND pcp.entity_table = 'civicrm_contribution_page' ORDER BY cp.title" key_field="id" value_field="title" />
