[PATCH] layer.conf: allow other layers to depend on this version

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Set LAYERVERSION and rename the collection to "core". Given changes such
as the tabs to spaces cleanup for python functions in the current
version, this allows other layers to depend on this version of OE-Core
specifically should they choose to do so, by specifying the following
in their own layer.conf:

LAYERDEPENDS_layername = "core:1"

Where layername is whatever value is being added to BBFILE_COLLECTIONS.

(This change does nothing unless a layer has LAYERDEPENDS set.)
