Added ServiceCategoriesMulti so that they are available for widgets

[alfredosilvestre-natixis]

Description

Hello,

This will add the functionality to list Service Categories that can be used in widgets or other parts of the application.

This is needed for this PR in the Service Monitoring widget and both these contributions will fix issue 78 of that repository.

Apart from the change in the code, there is also a need to add a field type in the database, but I don't know where to place this:

INSERT INTO `widget_parameters_field_type` (`ft_typename`, `is_connector`) VALUES ('serviceCategoriesMulti', '1');
