[sword-devel] Determining the repository a SWModule belongs to

Currently the engine does not intentionally preserve any information about
where a module comes from. This is why, for a single installer, it cannot
handle having parallel installs of the same module from different sources
(e.g. you can't have both CrossWire KJV and your own homegrown KJV in
parallel without giving your own a different module name).

There's nothing stopping an application from creating different local
repos, one for each upstream, and then combining the two using its own
logic. However, this isn't something the library currently supports. The
fact that you can reverse engineer its source, at present, is only because
none of the main repositories duplicates module identifiers from any other
repositories. However there is nothing, technically speaking, that prevents
this. Thus, module pedigree is not, necessarily, a deterministic thing.
