use default-to-passwordless behaviour if bind address is set to localhost, and recognize IPv6 loopback device (important for BrooklynNodeIntegrationTest to pass)
add a new --noGlobalBrooklynProperties CLI argument, and update the integration test to use it (means existing brooklyn.properties will not be used by tests or overwritten by BrooklynNode, unless specified otherwise)
temporarily disable the @Catalog annotation on enrichers, since these generate warnings now at runtime (as they are not policies).
this commit can be reverted when enrichers are supported in the catalog.
fix unit test for inferring filename
support DELETE method in the swagger ui, and hide the response class if it is the default ("ok")
add a single-main-container div around single pages, to support skins which define a different background colour
refactor localhost ipv6 checks as per svet's comments
This closes #163
