Add support for Plone resource overrides

[malthe]

This adds support for overriding static resources as registered by plone.resource.

Note that in principle this could live in a new "plone.jbot" package, but since we already have support for Zope 2 CMF objects (when Zope 2 is present), it is considered to be a reasonable inclusion here.

@malthe This is excellent work! We really missed this feature. See https://community.plone.org/t/missing-feature-override-static-resources/11307 or https://community.plone.org/t/how-to-customize-the-favicon-of-a-plone-5-2-site/9110.

Now we can for example override index.html, rules.xml or the favicon from plonetheme.barcloneta using jbot without having to create a custom theme in the filesystem or in the database.

I owe you a 🍺

This has been released as version 1.1.0.

@pbauer Could you elaborate how to proceed? Thanks.
