[yocto] [layerindex-web][PATCH v2 09/12] layerindex: Add collection and version to layerbranch

[Liam R. Howlett]

Collection and version will be pulled from the layer.conf if it exists
and dependencies will be resolved by first checking for layers with the
dependency name and then checking for collections.  It is necessary to
shutdown tinfoil to avoid bitbake complaining about multiple instances.
