Draft: new Draft_OrthoArray command

It replaces the older `Draft_Array` command, and provides
a task panel to select the properties, similar to the
`Draft_PolarArray` and `Draft_CircularArray` commands.

It can also create `App::Links` directly from this task
panel, so it also replaces the `Draft_LinkArray`
introduced by the LinkMerge.
