includes/dashboard.inc - Salesperson / Salesmen

I believed this was fixed where **Salesmen** was replaced with **Salesperson** to de-genderize the entity.

includes/dashboard.inc - Line 186

```
echo "<div class='square square1'>"._('Salesperson')."<p class='span1'>";
echo "<div class='square square1'>"._('Salesmen')."<p class='span1'>";

```
