inserting plugins and top-level items into sh

[Morg42]

At the moment, during initialization of shng,

first, each plugin is inserted as shng.<plg_section>,

second, each top-level item is inserted as shng.<item_top_path>

This has lead to collisions, at least for me. So, as there is no check if plugin identifier or item path are already present, the previous is overwritten by the latter.

Proposal:

1. to not change anything, leave the system in place (at least for now)
2. create a namespace (empty object? plugins/items class?) below shng
3. create plugin/item references in these namespaces

So, instead of (in addition to...) sh.<plugin1>, sh.<plugin2>, sh.<item1>, sh.<item2>, we would be able to use sh.plugins.<plugin1>, sh.plugins.<plugin2>, sh.items.<item1>, sh.items.<item2>

Caveat: if using lib.plugins and lib.items as namespace, make quite sure that plugin/item names don't overwrite plugins/items members (easy to implement...)

Pros:

• structured access
• collision free (in regard between items and plugins)
• nonbreaking
• cleanup for later; dynamic plugin unload might remove ref to item/item tree (!))

Cons:

• collisions still possible with namespace methods
• larger memory footprint, though probably neglectible, (# of plugins + # of top level items) * ref size

Any comments or ideas?

Implementation is fairly simple and already mentally prepared ;)

While trying to implement this, I found that items are already referenced in sh and sh.items, so this just does the same for plugins.
