API: Project ordering

Added support for ordering and sorting projects by id, name, created_at or last_activity_at fields.

When the order_by parameter is passed the projects will be ordered by the appropriate field, when the parameter is not passed the original ordering will apply.

the sort parameter will default to ASC, and will only be DESC if the sort parameter is desc

See merge request !266

Changed from using cases to set the sort variable, to use a one line if/else statement

Added support for order_by and sort parameters, to sort the projects by the specified values.
