 HTML API: Add custom text decoder.

 Provides a custom decoder for strings coming from HTML attributes and
 markup. This custom decoder is necessary because of deficiencies in
 PHP's `html_entity_decode()` function:

   - It isn't aware of 720 of the possible named character references in
     HTML, leaving many out that should be translated.

   - It isn't aware of the ambiguous ampersand rule, which allows
     conversion of character references in certain contexts when they
     are missing their closing `;`.

   - It doesn't draw a distinction for the ambiguous ampersand rule
     when decoding attribute values instead of markup values.

   - Use of `html_entity_decode()` requires manually passing non-default
     paramter values to ensure it decodes properly.

 This decoder also provides some conveniences, such as making a
 single-pass and interruptable decode operation possible. This will
 provide a number of opportunities to optimize detection and decoding
 of things like value prefixes, and whether a value contains a given
 substring.
