SUGGESTION: Allow encodeAs attribute on sec: taglib tags

[U47]

Currently, it appears all the tags in the sec: taglib very explicitly call encodeAsHTML() on any output they return.
https://github.com/grails-plugins/grails-spring-security-core/blob/071b036101fc2a20f71816ece9fc603caff74a80/plugin/grails-app/taglib/grails/plugin/springsecurity/SecurityTagLib.groovy#L124

There are uses for having the tags return results in other encodings. For example, returning an MD5 hash of the logged-in user's email field to send direct in a Gravatar image link. Or even returning as raw so that the hash could then be computed manually on a non-HTML encoded email address (which changes the @ to an HTML entity).

Because the tags are explicitly handling the encoding, using raw() doesn't help—the output has already been encoded by the time raw() can get it. The canned Grails tags (g:) supposedly (according to documentation) support an encodeAs attribute to override the default encoding. That could also be an option.

For your consideration. Thanks!
