[ARIES-1503] Another fix and small refactoring
The trick is to remember loaded resources and recognize 'bad' behaving
namespace handlers, i.e. those that always return the same url, irrespective of
the resource trying to be loaded. If a loader returns an already loaded url for
a resource, we ignore those.
In order for this to work, we also need to be smarter about identifying similar
resources. We need to cope with the fact that a schema can be imported with or
without a location for example, so we ignore the systemId when the schema is
imported. If the resource has already been loaded, quickly return the
previously loaded resource.
The blueprint container is also fixed wrt to added namespaces. The handler set
now do a copy of the schemas, and we use those to find missing namespaces.
Whenever a handler is removed, we can't easily find out which namespaces have
been dynamically added, so we simply recreate the handler set completely.

> Project: Aries
> Issue Type: Bug
> Components: Blueprint
> Affects Versions: blueprint-core-1.5.0, blueprint-parser-1.4.0,
> blueprint-cm-1.0.7
> Reporter: Grzegorz Grzybek
> Assignee: Jean-Baptiste Onofré
> Fix For: blueprint-core-1.6.1, blueprint-cm-1.0.9
>
>
> Since version 1.0.6, blueprint-cm's XSDs started to import ext namespaces, to
> reflect Java hierarchy of
> {{org.apache.aries.blueprint.compendium.cm.CmPropertyPlaceholder}} and
> {{org.apache.aries.blueprint.ext.PropertyPlaceholder}}, however, sometimes we
> fail with:
> {noformat}
> org.xml.sax.SAXParseException; systemId:
