The translation of `%ss` doesn't make sense
The function `on_before_render()` of the concrete5_Controller_Dashboard_Workflow_Me class contains the code `t('%ss', …)`, where the … may be `Page`, `File` or `User`.
Anyway, with that code, translators have to literally translate `%ss`, which doesn't make sense: only in English plural forms are composed by adding an 's' after a word (and even in English this is not always true).
My solution is to translate every case.
Another, more elegant solution, would be to change the /web/concrete/config/install/base/permissions.xml file, adding a new xml attribute (let's call it `tabName`) containing the text for the tabs for each one of the `category` nodes of the `workflowprogresscategories` node. This implies we have to modify the function `importWorkflowProgressCategories()` of the /web/concrete/core/libraries/content/importer.php file and the `Concrete5_Model_WorkflowProgressCategory` class to manage this property.
