fix: independant HTML implementation

[afu-dev]

This PR fixes bugs with the XML implementation, regarding tags and attributes. It also add an independant interpreter for the HTML implementation.

Here's a before/after:

XML

Note: tags, XML or HTML, cannot start with a digit or an hyphen.

HTML

Notes:

• compared to XML, tags must start with [a-z] and cannot use anything beside an hyphen.
• this PR fixes HTML attributes not highlighted if unquoted #173 for unquoted attributes

Current known bugs / regressions

Note: boolean attributes don't work (cannot work?) with the current regex implementation. Also if the string value contains an equal sign, the word before get highlighted (thanks to unquoted attributes).
