fix name typos in "creating yaml" instructions, and revert to `provisioning.properties` because that does work, confirmed by a unit test. not sure what happened yesterday when it didn't work for me!
tests and notes for #1377 which `location` tag in yaml dominates (currently the parent)
give cleaner error messages in GUI when parallel tasks (start) fail, esp for case of No locations being supplied (easily done in YAML)
fix VanillaSoftwareProcess ability to download and unpack archives. @grkvlt can you sanity check this please?
make the restarter policy work for bash, and add bash entity policies to the doc (and make the doc now read as though complete, though we still do want to add sensors and chef, and tweak how it looks also)
use a netcat server rather than a sleep for the bash example
unify how specs are resolved, including policySpec and enricherSpec, including supporting "policy_type" or "type" as well as the standard "policyType"
(in part because new CAMP spec switches to "_" separator)
add support for referencing initializers in yaml, with tests, plus more cleanup/dedup of how "decoration" types are constructed for entity specs
merged
make MulitLocation obtain across its sub-locations, so that yaml can combine locations with different credentials.
update docs for yaml locations, and for other parts of yaml reference including brooklyn.initializers.
