Added countItems to com_contact helper file

[pe7er]

This patch creates in "Category Manager: Contacts" 4 new columns with the number of contacts per category. It contains a helper file for com_contacts that is used in com_categories to calculate the number of contact items (published, unpublished, archived, and trashed) in each category. Note This patch works only in combination with #6916.

Test instructions:

The Category Manager: Contacts (Components > Contacts > Categories) does not display the number of Contacts in each category.

Create some new Contacts that are unpublished, trashed & archived.
Install both #6916 and this patch (the order of installation does not matter, you just need both).
After installing the patch, The Category Manager: Contacts (Components > Contacts > Categories) should displays 4 new columns.

Please also check this patch with the Hathor admin template.
