Adding a new key to the context based on a metadata key

Obfuscate text for use in web pages
; Replaces each character with an HTML escape code like "&#x20;".
; This is useful as some lightweight protection against e-mail harvesting;
; it probably won't perform correctly with non-ASCII input.

; example:
; (obfuscate "example.com")
; => "&#x65;&#x78;&#x61;&#x6d;&#x70;&#x6c;&#x65;&#x2e;&#x63;&#x6f;&#x6d;"
