Allow multiple caplitalized words (like typical vendor names) in ACL resource IDs

[samtay]

The current xsd schema allows for a single capitalized word, followed by an underscore, followed by any mix of lowercase and uppercase letters. All of this is followed by :: and another, more specific string that can contain a mix of lowercase and uppercase letters. For example,

<resource id="Magento_Catalog::attributes_attributes" title="Product" sortOrder="30" />

However, it seems that common practice will be to use the module name Vendor_Module as that first section of the id attribute. Since it is very common for vendor names to be two capitalized words, I've updated the schema to allow for something like below.

<resource id="BlueAcorn_UrlTracker::urltracker" title="URL Tracker" />

To be clear, with the original xsd, the resource ID would have to be Blueacorn_UrlTracker::urltracker, which would cause inconsistent naming across the application.

👍 I've also been meaning to send a PR for this :)

@Vinai Thanks Vinai! Big fan of yours, much of my Magento knowledge comes from your stack overflow answers.

@vpelipenko Any reason this hasn't been merged yet? Do you need anything else from me?
