Use JTidy for HTML

[JLLeitschuh]

It's tidy but implemented in Java. May be a very old artifact though.

That artifact is from July 2010. HTML5, released in 2014, requires some tags to not be closed, e.g. img, input, br, hr, meta. Maybe JTidy handles these correctly?

Whether it does or not, if its useful to somebody and easy to integrate, I'm all for adding an HtmlExtension, and people can add formatters as they desire.

The WDT also handles HTML/JS. Adaptations for HTML 5 have been provided, but I do not now how good they are.
If you guys are interested, I can extend #230 correspondingly and call it Spotless Eclipse-WDT instead of Eclipse-XML plugin.

As agreed with @nedtwigg , I will provided a Eclipse-WDT instead of Eclipse-XML which will also include JS/HTML5 formatting.
This is not considered a replacement of JTidy, but an additional option.

@JLLeitschuh Please have a look whether #315 fixes this issue. Note that the HTML formatter should be used for XHTML and not the XML formatter. The default includes of the xml/html extensions are set accordingly.

I don't actually have a use case currently so I can't really weigh in any more.
