#4: [git] quickfix for HEAD
Merge branch 'a.r.openerp-1.9' of github.com:anybox/anybox.recipe.odoo into a.r.openerp-1.9

the buildbot reorg is merged into master (less conflicts downstream)
Should have pulled first...
#4: [git] unit test for HEAD switching branches
[doc] revert is also implemented for git
[git] branch indication for SHA pinning
[git] avoid refetching SHA-pinned commit if already available

Call get_object_reference from ir.model.data registry using common external_id
