Remove the idea of a component from the jlog code

There is a reasonable amount of code in the logging to support the idea of a component.  I think the aim was to be able to indicate from which dll the logging was coming.  It is confiured to allow up to 1000 components, but only 3 are used (plus a duplicate in dfuwu)

It is never reported by default, and not really filled in.  Much clear to delete it, shrink the size of the interface and delete the associated classes.
