Extend the scope to 'deployment, instatiation and initialization time of 
a block'

May I raise the following questions:

1. Is there a need to have the freedom to indvidually name the root
    sitemap of a block other than 'sitemap.xmap' (I think you can still
    mount sub sitemaps which dont follow that naming pattern)?

If you answer is NO why don't we stick with 'CON-INF/sitemap.xmap'

2. Is there a need for dividing the component configuration of a block
    into multiple files which need to be included (isn't it better to
    split up the block into smaller piecies)?

If your answer is NO why don't we stick with META-INF/block.xconf

I've missed to place the dependant jars of a block. So I propose they go 
to META-INF/lib with no strong agruments for it but they are needed 
to setup the classloader for the block or to populate the parent 
classloader and that's done at initialization time.

WDYT?
